(MT5) Need help with setting up orders in Grid

New comment
 

Hello I am learning mql5 language. I have designed a code to setup pending orders in gird when a candle is bigger than the predefined range. If candle is bullish then place 1 sell trade and then set a specific amount of sell limit orders based on open price of the Sell trade and opposite for buys.

When anyone of the trade reaches the TP I want to close all orders and positions. Please check my code and help me improve it.
