Please help me! After starting the program, it works until the purchase is made, and then it returns an error. python main.py --account binanceaccount1 --exchange binance --pair BTCUSDT --strategy Sample about alpha-rptr

Hello, this error is regarding proper decimals/rounding which the exchange is expecting you to make before sending orders, in your case it seems you are using a market order, therefore there isnt an issue with the price level(limit orders could trigger this error for the limit parameter not being properly rounded) but quantity, respectively the size of your order. Basically every pair has different precision specification, so you need to take care of proper rounding in your case it would be rounding the quantity qty parameter in self.exchange.entry("Long", True, lot/20) entry function call, both for long and short entries. You could round the lot calculation lot = self.exchange.get_lot() like this for instanace lot = round(self.exchange.get_lot(), 3), which should round the lot quantity calculation (which is based on your balance) to 3 decimals.

Thank you, it's me who needs to make a change to strategy.py?

For now, yes you need to modify it yourself and use round_decimals parameter in function calls for other functions as well, when available. I will update the documentation eventually, there is a lot of changes coming so it will be a part of a major update sometime in the future.

Hello, You can show in the code where you need to make a change to make the program work correctly, thank you in advance!

Please be more specific about which strategy you would like to use and what exactly do you want. Is it only the rounding issue or do you need help with utilizing other functionality? Actually I would prefer, if we could talk in more detail on the dedicated discord server, because its more practical for instructions of that sort, please join https://discord.gg/ah3MGeN this discord server, if its not a problem for whatever reason. But in general you find lot variable in strategy.py in your chosen strategy class and inside of strategy function definition, usually among the first couple of variables. Then you can change it the way i described above or modify it to more closely meet your criteria.
