Indicator Correlation between 2 Symbols

I want to develop an indicator for MT4 Correlation similar to this demo I'm sending.

This demo is for MT5 and is valid until 2020-01-10 but if you use backtest with earlier date it will work for you. Observe how it works

I do not have the .mq5 file

indicator plots on a sub window the Price Line Close of 2 different symbols around level 0      Does not repeat and has no delay

I want the indicator to work in exactly the same way as the demo indicator and with the same options by adding a few more:
