Max spread

[AlexeyRoss]

Hello guys, help me please, what mt4 script Should looks like if i need this option for expert:

MaxSpread=30

Step for spread=10

So if spread is going more then 40 or below 20 - ea stop trading

Thanks in advance

Like this maybe?

int spread=SymbolInfoInteger(_Symbol,SYMBOL_SPREAD);
if(MathAbs(spread-MaxSpread)<=SpreadStep) OpenTrade();
