[Al Amri]

any one clarify ??

// Open a sell order

        ticket = OrderSend(_Symbol, ORDER_TYPE_SELL, lotSize, SymbolInfoDouble(_Symbol, SYMBOL_ASK), 3, 0, 0, "Sell Order", magicNumber, 0, Blue);

This is MT5	bool OrderSend(const MqlTradeRequest&,MqlTradeResult&)
This is MT4	ticket = OrderSend(_Symbol, ORDER_TYPE_SELL, lotSize, SymbolInfoDouble(_Symbol, SYMBOL_ASK), 3, 0, 0, "Sell Order", magicNumber, 0, Blue);

You posted in the MT5 general section. Decide which language you are using and code in that language.

could you please give code for this line only for MT5 version below : 

        ticket = OrderSend(_Symbol, ORDER_TYPE_SELL, lotSize, SymbolInfoDouble(_Symbol, SYMBOL_ASK), 3, 0, 0, "Sell Order", magicNumber, 0, Blue);

You don't replace just one line, it must be rewritten. MT4 only has orders (pending and open). MT5 has orders, deals, and positions.

No, not all good. That one line shows that a large part of your code is not compatible with MQL5.

You probably generated it using ChatGPT (or other A.I.) which produces horrible code, mixing MQL4 and MQL5.

So, please don't request help for generated code. Learn to properly code in MQL5 or hire a programmer in the Freelance section.
