Add indicator (filter) to buy sell condition in Amibroker AFL

I have a Amibroker AFL I want to add indicator as filter to the signal to reduce whipsaws, Indicator is ready and when added is not giving signal at required place, Coder need to modify condition to get signals at proper place Filter indicator : Plot buy only if price closes in blue ribbon and plot sell only if price closes in red ribbon main system afl and indicator code _SECTION_BEGIN("EASY FINAL HEIN"); HACLOSE=(O+H+L+C)/4; HaOpen = AMA( Ref( HaClose, -1 ), 0.5 ); HaHigh = Max( H, HaOpen ); HaLow = Min( L, HaOpen ); _SECTION_BEGIN("SmmA"); per=Param("Major MA",5,5,200,10); mmaH=EMA(H,per); smmaH=EMA(mmaH,per); mmaL=EMA(L,per); smmaL=EMA(mmaL,per); mycEH=IIf(HaClose>smmaH,colorBlue, IIf(HaCLose<smmaL,colorRed,//31)); IIf(HaClose<smmaH AND HaCLose>smmaL ,colorYellow,31))); _SECTION_END(); _SECTION_BEGIN("Trend Reversal"); TDO = Open; // current open TDH = High; // current high TDL = Low; // current low TDC = Close; // current close PDO = Ref(Open,-1); // last candle Open PDH = Ref(High,-1); // last candle high PDL = Ref(Low,-1); // last candle low PDC = Ref(Close,-1); // last candle close slow = LLV(Low, 21); shigh = HHV(High, 21); Plot(shigh,"",colorYellow,styleLine); Plot(slow,"",colorYellow,styleLine); bull=((H-L)/2)+L; bear=H-((H-L)/2); BRev = TDL == LLV(Low, 11); SRev = TDH == HHV(High, 11); BTR = PDL == LLV(Low, 11); STR = PDH == HHV(High, 11); BB = Ref(Low,-1) == LLV(Low, 11); SS = Ref(High,-1) == HHV(High, 11); BuyX= BRev AND PDL>TDL AND TDC>PDC AND TDC>TDO AND C>bull; ShortX= SRev AND PDH<TDH AND TDC<PDC AND TDC<TDO AND C<bear; BuyY= BTR AND TDO>PDC AND TDC>TDO AND TDL>PDC AND C>bull; ShortY= STR AND TDO<PDC AND TDC<TDO AND TDL<PDC AND C<bear; BuyZ=(BB AND Ref(L,-1)<Ref(L,-2) AND Ref(L,-1)<L AND C>Ref(H,-1)) OR (BTR AND Ref(L,-1)<Ref(L,-2) AND Ref(L,-1)<L AND C>Ref(H,-1)); ShortZ=(SS AND Ref(H,-1)>Ref(H,-2) AND Ref(H,-1)>H AND C<Ref(L,-1)) OR (STR AND Ref(H,-1)>Ref(H,-2) AND Ref(H,-1)>H AND C<Ref(L,-1)); Buy= (BuyX OR BuyY OR BuyZ) AND HaClose>smmaH; Sell=L < Ref(LLV(L, 11), -1); Short= (ShortX OR ShortY OR ShortZ) AND HaCLose<smmaL; Cover=H > Ref(HHV(H, 11), -1); Buy=ExRem(Buy,Sell); Short=ExRem(Short,Cover); Sell=ExRem(Sell,Buy); Cover=ExRem(Cover,Short); PlotShapes(Buy* shapeSquare,colorSkyblue, 0, L, Offset=-40); PlotShapes(Buy* shapeSquare,colorSkyblue, 0,L, Offset=-50); PlotShapes(Buy* shapeUpArrow,colorBlue, 0,L, Offset=-45); PlotShapes(Short* shapeSquare,colorPink, 0, H, Offset=40); PlotShapes(Short* shapeSquare,colorPink, 0,H, Offset=50); PlotShapes(Short* shapeDownArrow,colorRed, 0,H, Offset=-45); PlotShapes(Sell*shapeHollowDownArrow,colorPink,0,L,-45); PlotShapes(Cover*shapeHollowUpArrow,colorSkyblue,0,H,-45); _SECTION_END(); _SECTION_BEGIN( "Price" ); SetChartOptions( 0, chartShowDates | chartShowArrows | chartLogarithmic | chartWrapTitle ); _N( Title = StrFormat( "{{NAME}} - " + SectorID( 1 ) + " - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) Vol " + WriteVal( V, 1.0 ) + " {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ) ); Plot( C, "Close", colorRose, styleCandle | styleNoTitle | ParamStyle( "Style" ) | GetPriceStyle() ); _SECTION_END();
