How to stop the "If" from repeating

[feng2088]

Can I have the order excuted once or twice the most when the EMA lines cross each other? I see too many trades after the lines cross. Thanks for your time.

if (CrossAbove(EMA(Fast), EMA(Slow), 1))
{

If( );
EnterLong();

Else if ( )
ExitLong();

}

Don't think you want the semicolin at the end of the first "if()"

feng2088, if you see to many trades probably because you try to reverse with for exiting long and then entering long, this is not needed as the Enter() method alone would achieve the reveral for you.
