AnNam RSI Cycle [PlungerMen]

This script improves the default RSI 14
1: it identifies regions of the RSI which are oversold and overbought by changing the color of RSI from white to red.
2: it adds additional reference lines at 20,25.. 75,80 to better gauge the RSI value
Finally, the coolest feature, the middle 50 line is used to indicate which cycle the price is currently at
A green color at the 50 line indicates a bullish cycle, a red color indicators a bearish cycle, and a white color indicates a neutral cycle.
The cycles are determined using the RSI as follows:
if RSI is overbought, cycle switches to bullish until RSI falls below 40 , at which point it becomes neutral
if RSI is oversold, cycle switches bearish until RSI rises above 60, at which point it becomes neutral
a neutral cycle is exited at either overbought or oversold conditions
