How to scan for stock that trend above a 200-day EMA in a specific period

[tigeroo]

Hi all, chanced upon this forum while googling for some trading indicator queries, and glad that I found this community. I am new to trading and thinkorswim, and has just started to look into a more systematic way of trading with a plan and a set of rules.

I was trying to backtest a strategy that scan for stocks which are trending above a long-period EMA 200 or 233 (meaning the stock price never falls below the EMA 200 or 233) over a 90 days period. Next is to look for pullback when the EMA13 crossover down the EMA34, but the stock price is still above the EMA233 line. Is there such a indicator for scanning pullback of a trending stock?

I manage to explore the scan filters in the thinkorswim scan>stock hacker section, which I set up to match 2 of the above criteria:
Study> MovingAverage_Scan : the close is at least 0.01% above 233 period EMA
Study> MovingAvgCrossover: 13 period EMA crosses below 34 period EMA price close

But I am unable to find any study that can scan for the criteria of the stock trending up and its price never falls below the EMA 200 or 233 over a 90 days period.

Appreciate if any experienced traders can help to advise... Thanks

Edited: just found this on reddit about trendline:

Not sure if it is applicable to use the code, and scan for stocks that fits the trendline criteria and also have its price above the EMA 233 over a 90 days period.

You can use a sum statement. Here is an example that looked for CCI up for 90 of the last 100 days. Just modify it to look for EMA instead
