Hi experts
on this forum i think a lot of experts are ready to help newcomers. I would like to thank all of them in advance. In the past also i have received solution to may problems and hope that this time also i will get solutions.
I have a very popular afl which i have downloaded from a website. I want to get buy and sell signals as per following conditions.
when red candle appears i should get down signal and when blue signal appears i should get up signals.
This is the afl code :
_SECTION_BEGIN("Long MA 34 week");
P = ParamField("Price field",-1);
Periods = Param("Periods", 170, 2, 200, 1 );
Plot( MA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
SetChartBkColor(ParamColor("Outer panel color ",colorBlack)); // color of outer border
SetChartBkGradientFill( ParamColor("Inner panel color upper half",colorWhite),ParamColor("Inner panel color lower half",colorWhite)); // color of inner panel
_SECTION_END();
_SECTION_BEGIN("jim berg volatility ATR STOP SYSTEM");
//AMIBROKER, VOLATILITY SYSTEM. Here is a sample AmiBroker chart
//demonstrating the techniques from Jim Berg's article in this issue.
//In "The Truth About Volatility," Jim Berg presents how to use several well-known volatility measures such as average True range (ATR) to calculate entry, trailing stop, AND profit-taking levels. Implementing techniques presented in the article is very simple using the AmiBroker Formula Language (Afl), AND takes just a few lines of code.
//Listing 1 shows the formula that the plots color-coded price chart, trailing stop, AND profit-taking lines, as well as a colored ribbon showing volatility-based entry AND exit signals. The relative strength index (RSI) used by Berg is a built-in indicator in AmiBroker, so no additional code is necessary. See Figure 3 for an example.
//LISTING 1
EntrySignal = C > ( LLV( L, 20 ) + 2 * ATR( 10 ) );
ExitSignal = C < ( HHV( H, 20 ) - 2 * ATR( 10 ) );
Color = IIf( EntrySignal, colorBlue, IIf( ExitSignal, colorRed, colorGrey50 ));
TrailStop = HHV( C - 2 * ATR(10), 15 );
ProfitTaker = EMA( H, 13 ) + 2 * ATR(10);
/* plot price chart and stops */
Plot( TrailStop, "Trailing stop", colorWhite, styleThick | styleLine );
Plot( ProfitTaker, "Profit taker", colorWhite, styleThick );
Plot( C, "Price", Color, styleCandle | styleThick );
/* plot color ribbon */
Plot( 1, "", Color, styleArea | styleOwnScale | styleNoLabel, -0.1, 50 );
