// Camarilla pivot point formula is the refined form of existing classic pivot point formula. 
// The Camarilla method was developed by Nick Stott who was a very successful bond trader. 
// What makes it better is the use of Fibonacci numbers in calculation of levels.
//
// Camarilla equations are used to calculate intraday support and resistance levels using 
// the previous days volatility spread. Camarilla equations take previous day’s high, low and 
// close as input and generates 8 levels of intraday support and resistance based on pivot points. 
// There are 4 levels above pivot point and 4 levels below pivot points. The most important levels 
// are L3 L4 and H3 H4. H3 and L3 are the levels to go against the trend with stop loss around H4 or L4 . 
// While L4 and H4 are considered as breakout levels when these levels are breached its time to 
// trade with the trend.
//
// WARNING:
//  - For purpose educate only
//  - This script to change bars colors.
