New help to get the average size of the candles in a lookback period

[hughred22]

I am trying to program a Extreme Reversal Candle Stick indicator. And I need to calculate the average size of the candles in a look back period.

In Thinkorswim, I wrote the script like:
input length = 50;
def AverageCandle = Average(Candlesize, length);

The script will calculate an average Candlesize in a 50 bars look back period from current bar. And then I can use AverageCandle to compare with the current Candle size.

How can I do that in Ninjas? I can not find a function like "Candlesize" in Ninjas and do not know how to write it.

Any help will be greatly appreciated.

Hello hughred22,
Thanks for writing in and I am happy to assist you.
Unfortunately there are no predefined functions in NinjaScript for calculating average candle size. However you can calculate it easily via custom code. A basic code will be like,

double avgCandleSize = (SMA(High, 50)[0] + SMA(Low, 50)[0]) / 2;

double currentCandleSize = (High[0] + Low[0]) / 2;

Please let me know if I can assist you any further.

Thank you for the quick reply. So I see you are using Simple Moving Average to get the 50 period high and 50 period low. But I am not really sure the logic here. Is your code simply like

double avgCandleSize = SMA(High, 50)[0] - SMA(Low, 50)[0];
double currentCandleSize = High[0] - Low[0];

Why you have to add them up and divided it by 2?

Hello hughred22,
My apologies, the division is redundant.

You code should fulfill your purpose.

Please let me know if I can assist you any further.

Could you just not use the SMA of Range?

Yes that is also possible.

Sorry I don't understand - what exact same thing are you looking for? If its a moving average of range please read the whole post?

I may have missed somthing also but I would have thought a 50 ATR would give what you are looking for.
