//Hi, I'm learning..
//I'm trying to write a simple (not for me ;) ) custom chart, can you help me? Thank's!!
//NB: YOU CAN PASTE ALL IN FORMULA EDITOR TO READ IN DIFFERENT COLOURS, IT'S CLEARER! ;)
//CONDITIONS:
//1- NEW 20bars high
//2- then price goes down; I want sell if/when price(Close) < OLD 20 bars high within 20 bars from the NEW high
//I WROTE:
Cond01=Ref(Cross(High,Ref(HHV(High,20),-1)),-1); //"yesterday" (one bar ago) a new 20bars High
MyPeriod = 20;
for( i = 0; i < MyPeriod AND i < BarCount; i++ )
{
Cond02=C[i] < ValueWhen(Cond01, Ref(HHV(High,20),-2)); //from "today" and within 20 bars Close < OLD 20bars High (the 20bars High of two bars ago)
}
PlotShapes( IIf(Cond01 AND Cond02,shapeDigit8,0) ,colorViolet, 0, H,30); //Amibroker plot number "8" if cond1 and 2 over the "today bar", while I want to plot "8"
//over the bar that goes under the old 20bars High; Which function can I use to do this?
//NB: FOR THE SAME PATTERN I WROTE A MORE "COMPLICATE" TEXT, WITH A WORSE RESULT (the same problem but with number "7" plotted farther from the cond1,
//because "today bar" is 20 days after the cond1; I WRITE IT BELOW:
//----------
Cond02=Ref(Cross(High,Ref(HHV(High,20),-1)),-20); // 20 bars ago new 20bars High
Cond03=Ref(C,-19) < ValueWhen(Cond02, Ref(HHV(High,20),-21)); // 19 bars ago C< old 20bars high (the 20bars high of 21 bars ago)
Cond04=Ref(C,-18) < ValueWhen(Cond02, Ref(HHV(High,20),-21)); // 18 bars ago C< old 20bars high (the 20bars high of 21 bars ago)
Cond05=Ref(C,-17) < ValueWhen(Cond02, Ref(HHV(High,20),-21)); // 17 bars ago C< old 20bars high (the 20bars high of 21 bars ago)
Cond06=Ref(C,-16) < ValueWhen(Cond02, Ref(HHV(High,20),-21)); // ...
Cond07=Ref(C,-15) < ValueWhen(Cond02, Ref(HHV(High,20),-21));
