AFL Syntax Error - PLz Help

aca_trader · #1 15th February 2008, 04:56 PM

Dear Friends,

I have got this AFL for TD- Sequential from Interent which I wanted to backtest. However, I am getting sysntax error for the last line "_Section_End();". I have corrected other syntax errors but could not correct this one. A showcase of my programming skills.

Can anybody please help me out?

Thanks & Regards,

Ashish,

The close brace for 'if' condition is missing in Line No. 130. Highlighted in red colour for you.

The AFL Formula Editor doesn't have in-built indentation. It would have helped to code AFL a much easier, had it been present.

Praveen.

if(ShowTDPoints)
{
PlotShapes(TD_Supply()*shapeSmallCircle, colorRed, 0, H, H*.001);
PlotShapes(TD_Demand()*shapeSmallCircle, colorGreen, 0, L, -L*.001);
///////////////////////////////////////////////////////////////////////////
y0 = StrToNum(NumToStr(ValueWhen(TD_Demand(), L)));
x = LineArray(0, y0, (BarCount-1), y0);
Plot(x, "", colorGold, styleDashed);
y0 = StrToNum(NumToStr(ValueWhen(TD_Supply(), H)));
x = LineArray(0, y0, (BarCount-1), y0);
Plot(x, "", colorGold, styleDashed);
}

Dear Aca

Try the AFL attached

I have removed every thing below the sell signal.
This should be good for backtesting... (Though not for charting)

I backtested it on NSE stocks from 1.1.07 till date ..
result 27% loss

Hi Ajax!

Thanks for the backtest.
However, I am not looking forward to using this system. I was just looking for some filters to a system I am testing and came across the Demark Book on Options Trading. Hence, thought to apply it as an additional input.

Hello ajax/aca_trader/praveen,

I need some help on setting up amibroker for backtesting. I am using the AFL which has been posted here and attached my backtest results. Kindly comment on the settings and what precautions need be taken for getting proper backtesting results.

Thanks in advance.

John.
