Simple AFL code for 5 EMA(High-Low)

Here the Idea is to design a basic 5 EMA(High-Low) system which could produce

Buy/Sell Signals whenever the candle crosses the 5 EMA(High/Low) lines

i.e A Buy Signal should produced when it crosses and closes above 5 EMA(High) line

and a Sell Signal should produced when it crosses and closes below 5 EMA(low) line

Buy = Cross(Close,EMA(High,5));
Sell = Cross(EMA(Low,5),Close);

Amibroker’s AFL code had been designed to implement this system with Green Arrows in

the charts indicating Buy Signal and the Red downward arrows indicating sell signal

PlotShapes(IIf(Sell==1, shapeDownArrow, shapeNone), colorRed, 0,High, Offset=-20);
PlotShapes(IIf(Buy==1, shapeUpArrow , shapeNone), colorGreen, 0,Low, Offset=-20);

Both the weekly and Daily charts are shown with buy/sell signals. Just like any other trend following

system 5 EMA(High-Low) also works bad when the trend is side ways and produce more mixed signals

And where there is a strong trend the signals are good and could generate good potential returns.

The Complete AFL code for 5 EMA(High-Low) Buy/Sell Trading system

_SECTION_BEGIN(“5 EMA High-Low”);
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( Close, “Close”, ParamColor(“Color”, colorBlack ), styleNoTitle | ParamStyle(“Style”) | GetPriceStyle() );
Buy = Cross(Close,EMA( High , 5 ));
Sell = Cross(EMA( Low , 5 ),Close);
PlotShapes(IIf(Sell==1, shapeDownArrow, shapeNone), colorRed, 0,High, Offset=-20);
PlotShapes(IIf(Buy==1, shapeUpArrow , shapeNone), colorGreen, 0,Low, Offset=-20);
Plot( EMA( Low,5), “5 EMA LOW”,ParamColor(“Color”, colorBlue ),styleNoRescale);
Plot( EMA( High,5), “5 EMA High”,ParamColor(“Color”, colorBlue ),styleNoRescale);
_SECTION_END();

Little modification is required. Please draw the 5EMA (High Low) Band.

Dear RajI have just modified your afl i.e.Buy = Cross(Close,EMA( Low , 5 ));Sell = Cross(EMA( High , 5 ),Close);and found more meaningful. Please do comment on this modification.

Its adds more value to the trading systemin minimizing the losses and producing avalueable system.

One more modification is required. Just open daily Nifty Chart and just watch 16-12-2009. it has given false signal. I do not know how to omit it but this type of false signal can be omitted.If possible then it will be great trading system.Thanks

More modification done in Buy sell.Buy = Cross(Close,EMA( Low , 5 ))OR Cross(Close,EMA( High , 5 )); Sell = Cross(EMA( High , 5 ),Close)OR Cross(EMA( Low , 5 ),Close);It works fine in hourly and daily chart. I have added your earlier Buy Sell signal conditionally because if turn around happened within the band then this conditional extension is required.

@ShyamWe should not try to create more buy/sell signals.As this would create a mess. The scope of creating a buy/sell signal is to identify turns earlier and to generate potential profits. If you include 5 EMA signals also then it would probably create a mess and finally ends in confusion(i.e should we have to believe this signal or not)

if the signal density is high then your profit potential is very low

Sir,

This code is not working. Giving the error at 1st & Last line. Error 31. Syntax error, expecting ‘)’ or’,’

Regards,

Dipak

Dipak,
It works fine for me. Its all the basic codings. So it should work in all versions of amibroker too

Hello Rajendran,

Please paste again full AFL with modification suggested by above members.

Or I should use below code.

=======================================================================
_SECTION_BEGIN(“5 EMA High-Low”);
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( Close, “Close”, ParamColor(“Color”, colorBlack ), styleNoTitle | ParamStyle(“Style”) | GetPriceStyle() );

Buy = Cross(Close,EMA( Low , 5 ));
Sell = Cross(EMA( High , 5 ),Close);

PlotShapes(IIf(Sell==1, shapeDownArrow, shapeNone), colorRed, 0,High, Offset=-20);
PlotShapes(IIf(Buy==1, shapeUpArrow , shapeNone), colorGreen, 0,Low, Offset=-20);
Plot( EMA( Low,5), “5 EMA LOW”,ParamColor(“Color”, colorBlue ),styleNoRescale);
Plot( EMA( High,5), “5 EMA High”,ParamColor(“Color”, colorBlue ),styleNoRescale);
_SECTION_END();
