Usage

The api methods always return a promise which you can use to call methods like .then(...) and .catch(...). Refer: Promises

Getting Started with APIs

var VortexAPI = require("@asthatrade/jsvortex").VortexAPI
var Constants = require("@asthatrade/jsvortex").Constants

var client = new VortexAPI("api_secret","application_id")


client.login("client_code","password","totp").then(async (res)=> {
    await run()
}).catch((err)=>{
    console.log(err)
})

async function run(){
    var order_book = await client.orders()
    console.log("order book", order_book)

    var positions = await client.positions()
    console.log("positions",positions)

    client.quotes(["NSE_EQ-22"],Constants.QuoteModes.LTP).then((res)=>{
        return client.place_order(Constants.ExchangeTypes.NSE_EQUITY,22,Constants.TransactionTypes.SELL,Constants.ProductTypes.INTRADAY,Constants.VarietyTypes.REGULAR_MARKET_ORDER,1,res.data["NSE_EQ-22"].last_trade_price,0,0,Constants.ValidityTypes.FULL_DAY)
    })
    .then((res)=>{
        console.log(res)
    }).catch((err)=>{
        console.log(err)
    })
}

Getting started with Feed

var JSONbig = require('json-bigint');

var VortexFeed = require("@asthatrade/jsvortex").VortexFeed
var Constants = require("@asthatrade/jsvortex").Constants

const wire =  new VortexFeed("access_token",true,true)

wire.connect()
wire.on("price_update",onPriceUpdate)
wire.on("order_update", onOrderUpdate)
wire.on("error",onError)
wire.on("close",onClose)
wire.on("connect",onConnect)

function onConnect(){
    wire.subscribe(Constants.ExchangeTypes.NSE_EQUITY,26000,Constants.QuoteModes.OHLCV)
    wire.subscribe(Constants.ExchangeTypes.NSE_EQUITY,26009,Constants.QuoteModes.OHLCV)
}

function onPriceUpdate(updates){
    console.log(JSONbig.stringify(updates))
}

function onOrderUpdate(update){
    console.log(update)
}

function onClose(reason){
    console.log(reason)
}

function onError(reason){
    console.log(reason)
}

Pnl Calculation Issue

@brisingr123 To Calculate the Pnl I Used the method that was shown in the documentation but this method gave incorrect results

`
let positionData = {"exchange":"MCX_FO","symbol":"CRUDEOIL","expiry_date":"2023-08-17","option_type":"CE","token":257369,"product":"INTRADAY","quantity":1,"overnight_buy_value":0,"overnight_sell_value":0,"overnight_average_price":0,"lot_size":100,"multiplier":100,"average_price":17,"value":-1700,"buy_value":3430,"sell_value":1730,"buy_quantity":2,"sell_quantity":1,"buy_price":17.15,"sell_price":17.3}

let ptype = "Long"

let ltp = 19

if (ptype == "Long") {
// when buy position is open
// Gain = (last_trade_price * quantity * lot_size * multiplier +overnight_sell_value ) - overnight_buy_value
let cpnl = (ltp * positionData.quantity * positionData.lot_size * positionData.multiplier + positionData.overnight_sell_value) - positionData.overnight_buy_value
console.log("cpnl for long position", cpnl) }
