ROC on an EMA

February 2nd, 2015, 12:35 PM

Can anybody please, help me out here?

I am trying to set up the ROC of an EMA indicator.

I had a sample link where they use it but I can't post links yet.

Thank you.

Thank you.

go to ROC setting and change its input to EMA, an example

Want your NinjaTrader indicator created, free?

actually ninja already has stddev indicator you just need to point input setting to ATR like so

I already tried that but I can't add EMA to the Inputs scroll box?

Is that even possible?

Here is a working example of the ROC EMA indicator Iam trying to get going:

Here's my rendition of a rate of change script. Plots the rate of change for the 5 period and the 252 period with some EMA smoothing.

Code

# Rate of Change Script
    # Coded by Eric Rasmussen
    # ericrasmussentx@...

# Bullish
    # 252 day ROC crosses above 5 day ROC and the next day is        still above 5 day
# Bearish
    # 252 day ROC crosses below 5 day ROC and the next day is        still below 5 day

declare lower;

input smooth = 5;

def roc5day = 
ExpAverage(((close - close[4]) / close[4]) * 100, length = smooth);

def roc252day =
ExpAverage(((close - close[251]) / close[251]) * 100, length = smooth);

def crossUp = roc252day crosses above roc5day;
def crossDown = roc252day crosses below roc5day;

# Plots 
plot roc252 = roc252day;
roc252.AssignValueColor(if roc252day > roc5day then color.GREEN else color.RED);
roc252.SetPaintingStrategy(paintingStrategy.LINE);
roc252.SetLineWeight(1);

plot zero = if !IsNaN(close) then 0 else double.NaN;
zero.SetPaintingStrategy(PaintingStrategy.LINE);
zero.AssignValueColor(if roc252day > roc5day then color.GREEN else color.RED);
zero.SetLineWeight(2);
zero.HideTitle();

plot downCross = if crossDown[-1] then 0 else double.NaN;
downCross.SetPaintingStrategy(PaintingStrategy.POINTS);
downCross.AssignValueColor(color = Color.RED);
downCross.SetLineWeight(3);
downCross.HideTitle();

plot downCross2 = if crossDown[-1] then 0 else Double.NaN;
downCross2.SetPaintingStrategy(PaintingStrategy.POINTS);
downCross2.AssignValueColor(color = Color.WHITE);
downCross2.SetLineWeight(5);
downCross2.HideTitle();

plot upCross = if crossUp[-1] then 0 else Double.NaN;
upCross.SetPaintingStrategy(PaintingStrategy.POINTS);
upCross.AssignValueColor(color = color.GREEN);
upCross.SetLineWeight(3);
upCross.HideTitle();

plot upCross2 = if crossUp[-1] then 0 else Double.NaN;
upCross2.SetPaintingStrategy(PaintingStrategy.POINTS);
upCross2.AssignValueColor(color = Color.WHITE);
upCross2.SetLineWeight(5);
upCross2.HideTitle();

AddCloud(0, roc252day, color1 = color.RED, color2 = color.GREEN);
AddCloud(0, roc252day, color1 = color.RED, color2 = color.GREEN);

thanks but not exactly I think

here is a working sample of what I am looking for:

https://www.whselfinvest.com/en/trading_strategies_03_rocema.php

On the actual page they show it with a basic line that changes color. If you click on the EXPLANATORY VIDEO
link you will see it again, this time with a HISTOGRAM kind of setting...

Basically I need a ROC for an EMA of 16 time periods.
