Subject: Generalized Price Required to Meet am Indicator Goal
I had posted this along time ago ...
You supply:
- The array in the first statement ( Assumedly Price )
- The Indicator in the Calc = statement
- The Goal in the Goal = statement
... It will return in Explore the value needed in the array in the
next bar to have the indicator meet the goal in the next bar.
This is set up for use with a typical MACD but can be easily modified
for use with any indicator you can design.
P0 = C;
Acc = 0.00001;
LVBI = LastValue(BarIndex());
Mult = 1;
for (i = 0; i < 10; i++)
{
If (P0[LVBI] >= 1)
i = 99;
else
{
P0 = P0 * 10;
Mult = Mult * 10;
}

}
P1 = Ref(P0, 1);
UpDn = 100 * P1[LVBI];
for (i = 0; i < 200; i++)
{
Calc = EMA(P1,12)-EMA(P1,26);
Goal = EMA(EMA(P1,12)-EMA(P1,26),9);
if (Calc[LVBI] < Goal[LVBI])
P1[LVBI] = P1[LVBI] + UpDn;
else
P1[LVBI] = P1[LVBI] - UpDn;
UpDn = UpDn / 2;
if (UpDn <= Acc)
{
j = i;
i = 99999;
}

}
Accuracy = 100 * (abs(Goal[LVBI] - Calc[LVBI]) / Goal[LVBI]);
Filter = BarIndex() == LVBI;
AddColumn(Mult, "Multiplier", 1.0);
AddColumn(Calc[LVBI - 1] / Mult, "Curr Ind Val", 1.9);
AddColumn(Goal / Mult, "Goal Ind Val", 1.9);
AddColumn(Calc / Mult, "Calc Ind Val", 1.9);
AddColumn(j, "Iterations", 1.0);
AddColumn(Accuracy, "Accuray (%)", 1.9);
AddColumn(Ref(P1, -1) / Mult, "Current Array", 1.9);
AddColumn(P1 / Mult, "Needed Array", 1.9);
