That's the "catch the falling knife" approach. The problem I came across using RSI and STO was that, even at way oversold levels, it could and would go lower.
The problem with those indicators is that they are based on price, so that means if the currency is trading sideways, the RSI and STO will start to turn up, regardless of the price. So before you know it, RSI is back in the 40s/50s and the price barely went up, only to go down lower and hit single digit in the RSI again.
Just my opinion, not knocking your strategy but that's what I came across.
To be successful in the trading game, find a sound strategy and then learn and understand the rules of your strategy.
