"Error Marge" is changed into "Ratio Tolerance" with a percentage,
for easier understanding.
Harmonic patterns are calculated trough ratio's between high's and low's.
Normally there are rather strict ratio's before a pattern becomes valid.
The "Ratio Tolerance" can give a bit more slack, the ratio's are pushed a bit
more (max 10%) so it is a bit easier to get "valid" patterns, very importantly,
closer to 0% you'll get more strict and valid patterns (but less), further from 0% -> 10%
you'll get more patterns, but they are less strict, less valid, less correct,
Thank you!
