Hi @Manga_Man
We have shared the condition logic, Refer to the image below:
The scanner will check for stocks where EMA20 has crossed above EMA50 on the 10th candle previous to the current candle and then EMA20 has been above EMA50 for the previous ten candles.
Note: Regarding the logic of " any of the last 10 candles crossed ema 50" we have shared it here Find if any of the last 10 candles crossed ema 20 - #2 by Streak
