// This strategy stands out by using two distinct RSI lengths, analyzing the differential between these to make precise trading decisions. 
// Unlike conventional single RSI strategies, this method provides a more nuanced view of market dynamics, allowing traders to exploit 
// both overbought and oversold conditions with greater accuracy.
