Force Index with ATR Channels

[djdalgetrades]

I was wondering if anyone could help me with adding ATR Channels as used in Keltner Channels around Alexander Elders Force Index indicator? I have the code for ThinkOrSwim below, I just don't know how to convert it to NT8.



input length = 13;


plot FI = ExpAverage(data = (close - close[1]) * volume, length);

FI.SetDefaultColor(GetColor(8));


def h = FI;

def l = FI;

def c = FI;


input ATR_length = 26;

input EMA_length = 26;

input displace = 0;

input multiplier_factor = 1.0;

input mf2 = 2.0;

input mf3 = 3.0;


def val = ExpAverage(c, Ema_length);


def average_true_range = WildersAverage(TrueRange(h, c, l), length = atr_length);


plot Upper_Band = val[-displace] + multiplier_factor * average_true_range[-displace];

Upper_Band.SetDefaultColor(GetColor(0));


plot Midline = val[-displace];

midline.DefineColor("Up", Color.DARK_GREEN);

midline.DefineColor("Down", Color.RED);

midline.DefineColor("Even", Color.WHITE);

midline.AssignValueColor(if midline > midline[1] then midline.Color("Up") else (if midline == midline[1] then midline.Color("Even") else midline.Color("Down")));

midline.SetLineWeight(2);


plot Lower_Band = val[-displace] - multiplier_factor * average_true_range[-displace];

Lower_Band.SetDefaultColor(GetColor(0));


plot Upper_Band2 = val[-displace] + mf2 * average_true_range[-displace];

Upper_Band2.SetDefaultColor(GetColor(0));


plot Lower_Band2 = val[-displace] - mf2 * average_true_range[-displace];

Upper_Band2.SetDefaultColor(GetColor(0));


plot Upper_Band3 = val[-displace] + mf3 * average_true_range[-displace];

Upper_Band2.SetDefaultColor(GetColor(0));


plot Lower_Band3 = val[-displace] - mf3 * average_true_range[-displace];

Upper_Band2.SetDefaultColor(GetColor(0));


plot UpSignal = if Upper_Band3 < FI then FI else Double.NaN;

plot DownSignal = if Lower_Band3 > FI then FI else Double.NaN;


UpSignal.SetDefaultColor(Color.UPTICK);

UpSignal.SetPaintingStrategy(PaintingStrategy.ARRO W_UP);

DownSignal.SetDefaultColor(Color.DOWNTICK);

DownSignal.SetPaintingStrategy(PaintingStrategy.AR ROW_DOWN);

Hello djdalgetrades,

While our supprt cannot make items for you we can advise on various topics if you wanted to learn NinjaScript. This would be a good item to learn with as it seems the calculation is just a few lines of math.

AddPlot would be needed to create plots to access previous bar data: https://ninjatrader.com/support/help...ghtsub=addplot

You can use the NinjaScript editor to create items: https://ninjatrader.com/support/help...nt8/editor.htm
