Hello Comrades! Can you please tell me what the error is, the compiler gives a warning about possible data loss(

An explicit type conversion is needed:

int ts = (int)SymbolInfoInteger(Symbol(),SYMBOL_TRADE_STOPS_LEVEL);

Thank you! I can't remember all these nuances of conversion))

Often it is this:SymbolInfoInteger that is misleading. That's why it's better to look in the help once again.

Please tell me what the problem is. The compiler does not give out any errors. In the tester, in most transactions all is well, but sometimes the error handler in the printer does not write the correct stops and open price writes with 6 decimal places: Invalid price (stop) OrderSendX(symbol=AUDCAD,cmd=SELL,volume=0.29,price=0.995120,slippage=50,stoploss=0.996470,takeprofit=0.991070)

The first thing that caught my eye was this code fragment, these two functions are the same

 int msl = (int) MarketInfo(Symbol(),MODE_STOPLEVEL);
 int stsl = (int) SymbolInfoInteger(Symbol(),SYMBOL_TRADE_STOPS_LEVEL);

the first is old, the second is new

Can you please advise whether an EA will continue to work if I change the profile in MT4? Or do all EA windows have to be open in the same profile to work permanently?

[fvdtrejder]

Good day dear programmers!

Is it possible to write a program in MQL4 that will draw a chart in the form of candlesticks according to calculated values at different timeframes? Maybe there are ready-made codes for such problems?

Tools => Settings

and do what you want...

Hello, could you please tell me how to prescribe in the set parameters extern timeframe selection? It would be exactly a selection and not to print manually.

Use ENUM_TIMEFRAMES enumeration type variable.
