This strategy uses a 21 period RSI with an overbought (RSI indicator is greater than) level of 60 (user defined) to determines long entries and an oversold (RSI indicator is less than) level of 40 (user defined) for shorts. It introduces a bar delay that starts counting when the RSI < Oversold or RSI > Overbought conditions are true, delaying the entry with the amount of bars determined by the user. The trading logic can be reversed, which seems to work better.
