@Moderator_3 We can do that for buying but for selling all 4 might be at the same time or at different times according to their targets. this cannot be done. As we are buying 4 different strike prices and selling after 20 points profit which depends on a lot of things whether it will be sold at the same time or not.

@Moderator_1 @Moderator_2 @Moderator_3 I am using smartapi-javascript And placing 4 order at same time. Every time while placing order generateSession is called. But Sometime generate session is giving Status 403 and out of 4 2 or 3 order are getting placed. What is solution for this?

@admin @Moderator_1 @Moderator_2 @Moderator_3 Please reply on my query
https://smartapi.angelbroking.com/topic/4276/inconsistent-behaviour-of-smartapi-javascript-for-the-same-input-showing-jwt-token-error-and-sometime-working-fine

for the PlaceOrder function below, if I pass the same input it gives a jwt-token error sometimes and sometimes it works fine.

'
let { SmartAPI } = require("smartapi-javascript");
const totp = require("totp-generator");

const PlaceOrder = async ({ apikey, user_id, totp_secret, password,tradingsymbol,Qty,transactiontype,symboltoken }) => {

try {
    const token = totp(totp_secret);
    
    let smart_api = new SmartAPI({
        api_key: apikey,
    });
    let data = await smart_api
        .generateSession(user_id, password, token)
        .then(() => {

            return smart_api.placeOrder({
                "variety": "NORMAL",
                "tradingsymbol": tradingsymbol,
                "symboltoken": symboltoken,
                "transactiontype": transactiontype,
                "exchange": "NFO",
                "ordertype": "MARKET",
                "producttype": "CARRYFORWARD",
                "duration": "DAY",
                "price": "0",
                "squareoff": "0",
                "stoploss": "0",
                "quantity": Qty
            })
        })
        .catch((err) => {
            console.log("error generating" , err)
            return {}
        });
    return data;
}
catch (err) {
    console.log(err.message);
    return {}
}

}'

I tried to to debug the error it shows problem in
'node_modules\smartapi-javascript\lib\smartapi-connect.js:178:40'

even generateSession method in node modules is getting every parameter right it throws error which is catch block
'self.generateSession = function (client_code, password, totp) {
let params = {
clientcode: client_code,
password: password,
totp: totp,
};
let token_data = post_request('user_login', params);

	token_data
		.then((response) => {
			if (response.status) {
				// console.log(response.data.jwtToken)
				self.setClientCode(client_code);

				self.setAccessToken(response.data.jwtToken);
				self.setPublicToken(response.data.refreshToken);
			}
		})
		.catch(function (err) {
			throw err;
		});

	return token_data;
};

'

This breaks the code and I am trying to place an order for multiple brokers and multiple users but because of this, the whole code breaks.
please give some solution for this.
