// 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.
