Exit on same bar issue

[nkrastins]

Hello,

I am backtesting a simple gap up strategy where I go long, if open > yesterday's close.
and exit when close > open.

gap = Open > Ref(close,-1);
pricefilter = Open > MA(open,10); // optional filter

Buy = gap;
BuyPrice = Open;
Sell = Close > Open;
SellPrice = Close;

Code itself works fine, but I noticed that some trades aren't being closed when condition is met, instead, they are executed on the next bar.

on 25th April $PEP opened at 186.5 and closed at $189.71, it should have been closed, but instead, it got closed on the next day.

I am using TC2000 EOD data.

Thanks

Thank you,

I did follow the instructions and I and did add: SetOption("AllowSameBarExit", True ); rule, but I am still getting an exit on the next bar.

It's actually weird, some bars, even before adding the function, it did exit on the same bar and some it didn't....

SetOption("initialequity",25000);
SetPositionSize(20,spsPercentOfEquity);
SetTradeDelays(0,0,0,0);
SetChartBkColor(colorwhite); // color of outer border
SetChartBkGradientFill(colorlightorange,colorPaleGreen,colorBlack); // color of inner panel
Plot( C, "Portfolio Equity", ColorBlend( colorBrightGreen, colorBlack ), styleGradient | styleLine, Null, Null, 0, -1 );

Buy = 1;
Sell = 1;

AddColumn(Buy,"Buy", 1.0 );
AddColumn(Sell, "Sell", 1.0 );
Filter = Buy OR Sell;

gap = Open > Ref(close,-1);
pricefilter = Open > MA(open,10); // optional filter

SetOption("AllowSameBarExit", True );
SetOption("HoldMinBars", 0);

Buy = Open > Ref(close,-1);
BuyPrice = Open;
Sell = Close > Open;
SellPrice = Close;

in portolio settings menu, I have enabled "allow same bar entry/exit signal"

Hope this helps:

Entry & Exit in same Candle

Please refer to Allow same bar exit section of System test settings window guide. Search the forum too (this is discussed several times). Also refrain from using ExRem() function while same bar exit is "on". Limitation of Exrem or Flip functions: It has nothing to do with the platform (in this case AB) but more to do with the logic of your strategy. As per definition, Exrem( ARRAY1, ARRAY2 ) removes excessive signals; returns 1 on the first occurrence of "true" signal in Array1 then returns 0 …

Did you run the code from THE MANUAL?

To exit same bar, you have to have ZERO previously open positions at the beginning of that bar, so position can be open and closed the same bar.
If position is already open, it will just be closed.

Debugging your formula is your task.

To get better understanding of what is happening in your code and how functions work, use advice given here: How do I debug my formula?

ok, exRem function worked here.
