Hi Leo

Based on having watched charts for years, I have often times noticed that legitimate double tops tend to make a higher high (tops) or lower low (bottoms) on the second top or bottom than the first. The average close of the second top however if measured across the candle directly before the new high (tops) and low (bottoms) along with the candle that printed the actual high or low is usually lower (for tops) or higher (for bottoms).

Maybe you can try building that into your screener and/or code and see if it improves results?
