Hi, I am completely new to AFL. I started learning it just a day back.
The below mentioned AFL is my first Jugaadu Afl.
Whenever I DragnDrop it on chart it gives valid signals.
But while backtesting it gives very erratic trades. At least I think so.


My logic is simple - 1. Buy when ever pivot breaches up and
2. Sell when ever pivot breaches down

_SECTION_BEGIN("Price");
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
Plot( C, "Close", ParamColor("Color", colorDefault ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );
_SECTION_END();

The AFL should be ok if works on the chart, but you need to check the periodicity in the Analysis settings window. Make sure that it is set as per the TimeFrame that you need it to work on.
