You can have this and any number of other “equity” charts defined and you can export them to file using Edit->Image->Export to file.
In the future there will be an option to have such charts saved together with the report automatically.

When doing Walk-Forward optimization, AmiBroker uses dates defined in WF settings page (temporarily overrides AA range). After finishing WF, the original range is restored.

Yes it works with short trades as well. Remember to enable SHORT trades in the settings!

Does applystop also work to cover a short trade?

I can get the both methods to work as a buy/sell combo, but a simple replacement of “Buy” with “Short” and “Sell” with “Cover” doesn’t seem to work. (also swapped the stop line around to be LowestSince, rather than HighestSince).

Code I’m trying is as follows

StopLevel = Param(”trailing stop %”, 3, 0.1, 10, 0.1 );

SetTradeDelays(0,0,0,0);

Short = Cross( MACD(), Signal() );
Cover= 0;
ApplyStop( stopTypeTrailing, stopModePercent, StopLevel, True );

Equity( 1); // evaluate stops, all quotes

InTrade = Flip( Short, Cover );

SetOption(”EveryBarNullCheck”, True );
stopline = IIf( InTrade, LowestSince( Short, Low ) * ( 1 - 0.01 * StopLevel ), Null );

PlotShapes(Short*shapeUpArrow,colorGreen,0,Low);
PlotShapes(Cover*shapeDownArrow,colorRed,0,High);

Plot( Cover,”Price”,colorBlack,styleBar);
Plot( stopline, “trailing stop line”, colorRed );

Could this kind of graphics/reports be included in the built in backtesting reports?
It would be very helpful, since the standard reports/charts are a little short in this type of information. Ex: weekly, monthly, yearly performance.

Does the range of quotes & dates set in the AA window have any effect when doing a WF Optimization, or do the WF dates over-ride the range selection?

Copy-paste artists usually forget about using SAME settings. Most probably you are using non-zero trading delays while the example assumes using zero delay.

I pasted these two types of AFL code into 2 different formulas, and quickly find that these two approaches generate different trade results in Backtest. Any ideas?
