//It seems to work well but still no guarantee on completeness!
//RISK WARNING! PAST PERFORMANCE IS NOT NECESSARILY INDICATIVE OF FUTURE RESULTS. IN MAKING AN INVESTMENT DECISION, TRADERS MUST RELY ON THEIR OWN EXAMINATION OF THE ENTITY MAKING THE TRADING DECISIONS!

//How it works:
//Minor Degree (one bar) (gray)= If the current high is higher than the previous high or the current low is lower than the previous low.
//Intermediate Degree (two bar) (baby blue)= If the current high is higher than previous and the penultimate high etc.
//Main Degree (three bar) (red)= If the current high is higher than the previous, the penultimate and the high before penultimate high.
//On crossover there will be an alert (popup with a message) and in addition you will see "diamonds" on the place where the crossover took place
//In the preferences menu you can turn the specific degrees on and off
