Hello.
Please help me the mql5 code of Contract Size.

For example:
Bid Price = SymbolInfoDouble(Symbol(),SYMBOL_BID)

I use SymbolInfoDouble(Symbol(),SYMBOL_CONTRACTSIZE) or SymbolInfoDouble(Symbol(),SYMBOL_CONTRACT_SIZE) or MarketInfo(Symbol(),MODE_LOTSIZE) still not work. It all got error "undeclared identifier".

Please help

@pheaktra-capo You can use market properties on MT4, not sure of others, probabily MT5: https://fxdreema.com/shared/waz9CgE7d

Hello brother. Thank for fast reply.
I want it to calculate with the Highest Price to Lowest Price of the BUY/SELL. The result is the BUY/SELL bucket distant.
So i need this Contract Size Mql5 to put in custom code block.
