Attention!

Active use of the extension can cause detection by the TradingView as using a bot for backtesting and lead to the ban of the user's account.

Although the extension is not a bot (i.e. it does not work independently of the user in the cloud), it does not use the TradingView API and does not interfere with data transmission, but only automates user behavior through the UI. Its use and all risks remain with the users.

Disclaimer

The developer of the extension does not response for any possible consequences of its use.

Functionality

Backtesting trading strategies, optimisation of the strategy's parameters:

• automatic getting a list of parameters and their types (numeric, lists and checkboxes are supported)
• generation of the testing range according to the rule: the beginning value is 2 times less than the current one, the end is 2 times more than the current one.
• saving the generated parameters of testing a trading strategy for their correction as a template in a file in CSV format
• Loading adjusted parameter ranges from a CSV file
• Configuring the optimisation model:
  • Choosing the type of optimisation: searching for the maximum or minimum values
  • Selecting an optimised value from the entire list of strategy results in Tradingview (Net Profit, Ratio Avg Win / Avg Loss, Sharpe Ratio, Sortino Ratio, etc.)
  • Choosing a search strategy in the parameter space(random, sequential, annealing method)
• Filtering of unsuitable results. For example, the number of tradings is less than necessary
• Setting the number of cycles to search for parameters.
• Performing automatic selection of parameters with storing all the results in the browser storage and the ability to save them as CSV files after testing, including in case of an error or page reloading
• Showing backtesting results on 3d chartto analyze the effect of various parameters on the result.

Optimization Methods

The sequential improvements optimization method is implement adjusting the best value already found. It does not perform a complete search of the entire parameter space. The logic of it work is as follows. The current best state (parameters for max results) is taken. The first parameter is taken and all its values in the range are checked sequentially. If the best result is found, then further verification is carried out from this state. Then the next parameter is taken and all its values in the range are checked and etc.

The brute force optimization method implement backtesting all values in strategy space of parameters.

The annealing method is an optimization method in which the search for the maximum possible result is carried out in fewer steps https://en.wikipedia.org/wiki/Simulated_annealing The method works this way: first, the best state and its parameters are determined. One parameter is randomly determined, then its value from range of possible values is randomly selected. The status in this value is checked. If it is better, then it is remembered and further parameter changes are made from it. As the number of tests increases, the spread of parameter values decreases around those already found. That is, if at the beginning of testing the values are randomly selected from the entire range of possible parameter values, then as optimization is carried out, this spread decreases ("cools down") near current values. So in first phase of test - this method is search the most possible state around all space on the finish stage this method trying to improve found best state. So that the system does not get stuck in one parameter area, as it happens with the sequential method, not one random parameter changes periodically, but all at once.

The random improvements method is the simplest. One parameter is randomly determined and then a value is randomly selected for it from the entire range of possible values. If the condition is better, then it is remembered. And then the parameters from this state are randomly changed.

The random method - always selects random values for all parameters at once (default)

Upload external signals to tradingview chart

Loading external buy or sell signals by timestamps from a CSV file*

To display the signals, you need to create a pine script named 'iondvSignals' from the script bellow add it to the chart:

//©akumidv
//@version=4
study("iondv Signals", shorttitle="iondvSignals", overlay=true)
strTSBuy = input("", "TSBuy")
strTSBuy = input("", "TSSell")
tickerName = input("", "Ticker")
var arrTSBuy = str.split(buy_series_time, ",")
var arrTSSell = str.split(sell_series_time, ",")
plotchar(tickerName == syminfo.ticker and array.includes(arrTSBuy, tostring(time)) ? low : na, location = location.belowbar, color=color.green, char='▲')
plotchar(tickerName == syminfo.ticker and array.includes(arrTSSell, tostring(time)) ? low : na, location = location.abovebar, color=color.red, char='▼')

After that, upload the signals from the file created accordingly the template

timestamp,ticker,timeframe,signal
1625718600000,BTCUSDT,1m,BUY
2021-07-27T01:00:00Z,BABA,1H,SELL

The signals are stored in the browser, to activate them, open the properties of the created indicator named 'iondvSignals'.

Setup

Install from Chrome webstroe

Or manually add the latest version to chrome based browser from this repository by following the instruction below.

Click on the browser's address bar, insert chrome://extensions and follow this link. Click on the "Developer mode" switch.

The "Load unpacked" button should appear. Click on it, and in the window that opens, select the folder with the saved repository files (you can download them as a zip archive via the link https://github.com/akumidv/tradingview-assistant-chrome-extension/archive/refs/heads/main.zip).

The manifest.json file is located in the root folder of the extension.

Update

Unpack the new version to the same directory as the previous version (it is better to delete the files of the previous version). Go to the extensions tab by following the link chrome://extensions. Click the restart button for the extension.

Issues

Please add issues in this repository by following link.

Very helpfull will be if you can attach full screenshot with tradingview page and errors. And also with open command tab in browser developer mode (please press F12 to open developer mode and click on console tab)

PS

** The field separator for CSV files is a comma.

Recommendation

If your strategy requires a large amount of testing, it is recommended to order its conversion into python and perform backtesting and hyperoptimization of parameters using resources, such as Google Collab or your computer. In addition, it significantly speeds up the search for parameters (in 5-10 times per cycle) and history deep. Examples in Jupyter Notebooks in repository trade-strategies-backtesting-optimization. You can run examples in Google Collab, it's free. You would just upload files with extension *.ipynb to your Google Drive and open these files.

Where transfering from TradingViews scripts usually developer should solve some promblems:

• Trading view indicators – some of them have different formulas to calculate results, for example supertrend, ta.RMA and more others. They need additional implementation and in results they calculated more slowly than if python script would use ta-lib.
• Implementation of the data parsing. If the data for the crypt is mostly free, but the data of low timeframes is usually paid (for example, eodhistoricaldata). Developer need to implement an interface to them and some process to store and reuse local(cloud) stored data.

• Difference in data for stock or forex exchanges from Tradingview. Also, for some cryptocurrency exchanges.
• Adopt framework of backtesting (backtesting, backtrader, vectorbot, etc.) to work with strategy
• Wrap this code for frameworks of parameter gyperspace optimization (simple example you can see in trade-strategies-backtesting-optimization) and increase speed of backtesting with some methods.

From my experience it demands 2-3 minutes developer time for each row of tradingview script. For example if you have 200 line strategy it would demand ~6 hours to conversion. For some complicated strategies it can deman much more.

To reduce developing time you can use some my repositories:

• tradingview-ta-lib - Tradingview ta lib implementation in python (only for tradingview indecators that have different caclulatoin results with ta-lib or python-ta - early developing stage.
• catcher-bot - Bot for screening all symbols on excahnges/exchanges and cath trade signals - early developing stage.

Problem with filtering

Hello, I have set up a filter with DD max 20% and also with % profit all. When I check the best setting with % profit all I have a max dd of 40%. Recurrence of the problem with version 1.6. thanks

No param detected

Error message keeps popping up

The extension keeps giving an error.

Thank you

Just wanted to stop by and say thank you!

No strategy name element on page

Since a few hours ago i get the error that the extension cannot find the strategy element on the page even though it is visibly open. I think it is because tradingview made some new changes again that the name of the HTML element got changed or something of this sort.
Screenshot with the error and strategy element open:

Screenshot with tradingview changes

I saved the html code of the page incase that could be useful for you aswell.

Missing column in CSV

Hello
I wanted to merge several CSV files to make one.
When I converted the files to Excel with the "," separation, I realized that the columns were not the same, depending on the file, some columns were missing.
Is it possible to have files with columns that match? Thanks

Removing column from the csv result

Hi

First of all, I would like to thank you for this fantastic backtester it's really impressive. I would like to know if it's possible to only show the column we want when your extension generates the CSV file? There is too much useless data for my own need and it would be awesome if we could just delete the column we don't want within the extension or with another method.

Thank

Add help icon to optimiztoin method, also add to readme and extension description.

Update Sample template

сбстн сабж, в линке зашит шаблон без default и priority
и если возможно добавьте описание этих полей

Cannot convert undefined or null to object

Расширение работает только если tradingview на английском, стоит это указать в описании или решить проблему.

Get Template and Test strategy don't detect & manage float params

"Get Template" functionality doesn't manage float values in the strategy parameters. Only integer?

e.g.

// @version=5
strategy(...)
i_multi = input.float(  title='Multiplier', defval=3.1, minval=0.1, step=0.1, group="COEFF", tooltip="Hello Folks!")

Affter a "Get Template", in the Excel I see:

Parameter | From | To    | Step | Default | Priority
Multiplier| 3.1  | 19.6  | 1    | 6.8     | 18

So, I forced Step value to 0.1 and imported into the addin the csv with the helpful "Upload parameters".
When I run "Test strategy", the popup list, that I can see before the execution, shows the active Multiplier param with a step value = 1 and only increments by 1 unit and no 0.1 as expected from the strategy code and from the "Upload parameters" command.
Is there something I'm missing or wrong?

Kind Regards

Extension does not detect some parameters.

Hello,
the extension does detect "AltFilter I and AltFilter II" but it doesn't detect numbers next to it so I am unable to change them in settings.

Also, it doesn't detect multiple "short" and "%" values and it show only one short and one %. So once again I cant change it in settings.


Would be possible to release update that will detect these values that I am missing?
But overall it's insane extension!

result is wrong!!!

Hello, even though the net profit is negative, it takes it numerically and affects the results negatively.

A pop-up window with a 3D graph of the two most correlated strategy parameters and the result (for example, net-profit)

https://github.com/akumidv/tradingview-assistant-chrome-extension/tree/3chart

enhancement: Add a button to copy the estimated cycles into the Cycles input-box in "Strategy parameters" popup

A helpful button (paste Icon) to copy the estimated cycles value [id="cyclesAll"] into the Cycles input box [id="stratParamCycles"].

Cycles, by default, is always 10.
Every time, I need to copy by myself the estimated value before to run the Strategy Test.

Deep History beta feature of TV completely broke the extension, can't find the strategies

The new feature that TradingView rolled out of Deep History broke the extension that can't find the strategy on chart and reports to load the proper page.

clean best results

this answer is kind of funny. I already know this button. I don't want everything deleted. I only want the best result values to be deleted. I want to keep the parameter settings.... understand?

Extension does not use steps lower than 1.

In the csv file you can specify the step with which the extension will go through the settings, but it does not go below a step of 1 anymore. I will attach a screenshot where it shows i use a 0.1 step for the Stop loss and Take profit but during the tests it only uses steps of 1. It used to work before so i dont know if i did something wrong or if something in the code changed that this isnt posible anymore. I tried to use both 0.1 and 0,1 and neither work.

Cannot read properties of undefined with filter-on for Annealing method

Very good change to have your extension!

I always got error of undefined properties during the backtesting when using filter. It happened to every strategies I tested, though there is no problem without filter (500-1000 iterations). The backtesting parameters could be run for few combinations (~3-10) before it stopped (both less/more filters). It seems some parameters value has gone or not updated during the test.

.

Possible to schedule running on cloud?

Hey,
Like alot of chrome extensions allow scraping on cloud, can we customize this as a paid feature for users?

Error message

I got this error message several times today.

Error during install of extension

Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist. Error occurs after using load unpacked of chrome extension.

Button for export trades and performance

Error message keeps popping up

I keep getting an undefined properies error message. how can i fix this? It happens for th Take profit factor as well as the length.

Show and set parameters for backtesting in popup window

NaN Error

Working yesterday - Not working today... Get this weird NaN error? Thanks

There is not strategy name element on page. Open correct page please

Just in, worked ok before 2 hours.
Using the "Deep History" layout.

Change the return object in functions to try/catch constructions and move output to controller.

enhancement: Add the option to uncheck ALL checkbox in "Strategy parameters" popup

I've many params to manage (above 50).
Very often I prefer to jump to the "Strategy parameters" window and manage the params directly without doing an export/save before and then import/upload into the addin just to see all the params unchecked apart the ones from the excel file.
When, for example, I change the name or I add a new param in my Strategy and click on "Test strategy" without doing before a "Get Template"/"Upload parameters" the "Strategy parameters" window opens with ALL the params selected.

So, It might be practical to have an option at the top of the checkbox column to quickly deselect everything so that I can only select the parameters I want to test and avoid deselecting all 50 and over parameters by hand first on my list.

Ability to test Watchlist & Timeframes (both or seperate) with static (or parametrization of the strategies)

There is an extension possibly based on yours (based on the design similarities)
ID: emcpjechgmpcnjphefjekmdlaljbiegp
of trader.dev
where there are the options :

1. To check the whole watchlist with current settings of the strategy
2. To check a set of timeframes for one pair
3. (my request) Possibly to check all watchlist pairs in all defined timeframes

The same goes for the Davidd ext. i mentioned before

pageMouseClickEL is not a function

I tryed to run the optimizer on a subset of parameters of a strategy but i randomly get the error pageMouseClickEL is not a function while running.
Does not seems to happen after the same amount of iteration, happens randomly.

Is it possible to stop it from downloading files after each result?

suggestion from user

Sharpe Ratio not fetched correctly

I was trying to optimize a strategy on sharpe ratio but look like the assistant is unable to fetch it corectly.

data error

Returns the error: "There is no data for conversion"

database or csv

Can you store the iondv key information in csv instead of chrome.storage.local? Although I changed the scanning parameters, it scans using the previous settings. I have to clear the parameters, refresh the page and change the parameters again...

or if you cancel the best starting values before starting the test I think my problem will be solved...

NaN error : minimized window size

Hello. I noticed that depending on the size of the minimized window there is the error NaN. Thanks

Artificial Neural Networks [ANNs] is it possible ?

As I wrote in the title, the annealing method is really nice. It will be much more successful if it can find the right result faster and with less repetitions.
-Also, if you add artificial intelligence to the project, I really get teary-eyed.
-and the project must have a time frame and be scannable.
-Can the right time frame be found first with artificial intelligence or annealing method?
These are the ones that come to my mind now. Thanks in advance. Actually I am a programmer but I know very little javascript.

How to take params from external indicator as data source for strategy under test?

I am looking for possibility to use parameters not from the strategy, but from the indicator, which serves as an external data source for the strategy under test. This is done using https://www.tradingview.com/blog/en/use-an-input-from-another-indicator-with-your-strategy-19584/
Is it difficult to support such feature?

Error message: Cannot convert undefined or null to object

Hi When running the optimiser the first run seems to run the second raises this error .

Error message: Cannot convert undefined or null to object

An error has occurred.

Reload the page and try again.
You can describe the problem by following the link.

Error message: Cannot convert undefined or null to object

hello

Hello

Wrong Cycles number in "Strategy parameters" when the param to be tested starts From 0 [zero]

Example:

float param [from 1 to 3, step 1] --> Cycles = 3 Ok!
float param [from 0.1 to 3, step 0.2] --> Cycles = 15 Ok!
float param [from 0 to 3, step 1] --> Cycles = 1 Wrong!
float param [from 0 to 3, step 0.1] --> Cycles = 1 Wrong!

Both integer and float params can't be tested if from is = to 0

Increase Cycles limit

Hello, Love your extension.
Is there a possibility to test all input parameters with permutation not sequential to be able to test all possible combinations?

Change Tradingview time interval.

Hello again, and thanks for this awesome extension. Is it possible to change settings in Tradingview with the extension? Specifically cycle through the starred (favorites) Time Interval. I would like to be able to run through some, but not all time variables when backtesting.

cqnnot get properties of undefined ALOT but only sometimes

happens on ATR and EMA which are the first 2 paremeters second 2 are just atr tp and atr sl

Annealing does not work

When you choose the option of Annealing in the optimizer it gives no data whatsoever. I can see in the strategy tab that it gives the correct % numbers but not in the optimizer screen. I thought it was just a visual bug but when the excel is downloaded it also shows that there was no data collected.

Results in CSV are not the actual ones and Optimum settings are not applied when cycle stops (manual or auto)

Your script is a daily buddy.
I put him to work and i like to see what he has for me at the end of it.
Something like a puppy with a bone, i through a bone and wait if it can get me iron, silver or gold.

Before few days everything was fine.
Today i noticed that the optimum settings that the popup window report didn't applied to the strategy, when i stopped it manual or the cycle ended normally.

I said OK, no big deal, i will go and sort the csv to find them.
However when i tried to put the settings to the script, the results still didn't match with the CSV.
I used Annealing and Random improvement with Profit Factor all and Net Profit all.

I have the CSVs if you think they can help you. The strategy was the "Grab Trading System"
It has only two parameters (long and short)

Not an issue

I'm trading with Jack Rabbit Tradingview suite of signals, it's a cool mudular signal system and normally the alerts are created on the signals and not on the strategies (the strategies are used only to backtest) due to the misfire that normally happens on singals on strategies expecially on fast timeframes.
I wonder is it's possble to use the assistant to change parameters of signals and check thesults on the strategy.
Thanks !

Tradingview has changed the interface again!

hi bro @akumidv !

Tradingview has changed the interface again!

Use range in filter?

Is it possible also to have range in filter? As GT or LT is only filter @ one side of the parameters while sometimes it should be more appropriate instead of that to specify in range.

Eg. there should be suitable Buy/Sell number of trades not more or less. If we trade too often it got chances that we will loss in accumulated little trades and if we trade too little it got more unreliable long periods for the indicators' time frame.

We can also use filter to imply second target such as max drawdown. In this case we would to minimize it at the same time I don't want it to be zero as it looks not feasible and proof inaccurate for long run.
