Converting MT4 indicator to Pine Script

I need a simple and short MT4 indicator converted to tradingview Pine Script indicator.

It needs to be the exact same type of indicator.

I have the MT4 source file (attached).

When converted to Pinescript, it needs to be:

1) the channel follows to the right of the current candle

2) load according to current timeframe

I will keep the pinescript source code. You need to send all source code.

This is private work and will remain strictly confidential. 

Thanks in advance :)
