Perfect signal by c00l75 v4

-- CONCEPT - HOW IT WORKS ---

This script is based on moving average crossing lines (mirrored) with a signal line.

--- WHAT IS DIFFERENT FROM OTHER MA SCRIPTS ---

It's different in the formula for calculating the moving averages. NOW the length of the moving averages is modifiable to permit the user to tuning system better.

--- WHAT IS IT FOR? ---

It's a trend following script. I needed a script to catch signals for medium term trading (5-20 days) on > H4 TF with smooth lines but pretty quick signal, possibly easy to manage and "plug and play" for Forex market.

--- HOW TO USE IT? ---

Simply you have buy or sell signal looking at crossing lines. Signal line could be used to catch retracements.

--- WHERE SHOULD I USE IT? ---

At the moment I tested it only on Forex market with good results on H1 timeframe. Backtest it by yourself before using it.

Hope I can help someone else to have better trading time. Feel free to comment if you have questions.

NOTE for moderators: It's the update version of a my previous script (Perfect signal by c00l75) to version v4 with added ability to change the periods of the user's choice. To do this I had to republish it because the previous one was an old version of pinescript that is no longer supported.
