Scan for last price a certain amount from EMA

[twokay]

So, my strategy revolves around the 8/9, 20/21 EMA's. How would I go about creating a scan that checks for stocks which last price are within a certain $ amount (either above or below) of the given EMA's? I would like it to be customizable in that the length, type, and timeframe of the averages can all be adjusted

I appreciate any tips or help in creating it. I have extremely limited knowledge of Thinkscript and have tried creating the scan based off the built-in moving average scan, but could not figure out how to do it.

Scan For Price Within A Certain Dollar Amount To EMA
@twokay Is this what you are trying to say? Find all stocks: where the difference of EMA8 - price is less than $22 or greater than -$22? (for example)

Create this study:

Input CertainDollarAmt = 22 ;
Input ema_length = 8 ;

def EMA = MovingAverage(AverageType.eXPONENTIAL, close, ema_length) ;
def diff = EMA - close;
plot scan = diff is less than CertainDollarAmt and diff is greater than -CertainDollarAmt ;

Then in the scanner: select the name of your study and set the middle column to: is true
