This happens because in ur formula u did not mention sellprice/coverprice.
U just mentioned sell/cover.
The exit will happen according to ur condition but since sellprice is missing, it ll take close of the candle as exit price.

List = CategoryGetSymbols( categoryWatchlist, wlnum ) ;

if ( Status("stocknum") == 0 )
{
StaticVarRemove( "rank*" );

for ( n = 0; ( Symbol = StrExtract( List, n ) ) != ""; n++ )
{
SetForeign ( symbol );
values = Roc( Close, 10 );
RestorePriceArrays();
StaticVarSet ( "valuesToSort" + symbol, values );
}

StaticVarGenerateRanks( "bot", "valuesToSort", -1, 1234 );
}

symbol = Name();

rank = StaticVarGet ( "rank" + "values" + symbol );

AddColumn ( rank, "AbsValues" );

Filter = rank <= 1;

Amibroker is really good, I have used multiple charting softwares but the kind of flexibility and power you can get in Amibroker is Unique. It is also super fast and easy to code with tons of examples all around.

I have licenses Amibroker v 6.10 and I will certainly recommend Buying it as it is worth it. In terms of Data you dont need e-signal, there are many cheaper options available that provide tick data at around 500 Rs per segment per month. That works well with Amiboker.

Happy Trading.
Ganesh
