Original study from LazyBear

Scope of this port is to identify corrects inputs to get best results from signals that indicator gives.
The squeeze gives a further filter before orders and avoid to enter in a flat market period.

I attached it to chart with heikin ashi candles to have a better result and remove noise: results are good.

Please use comment section for any feedback.
Next improvement (only to whom is interested to this script and follows me): study with alerts on multiple tickers all at one. Leave a comment if you want to have access to study.
