Convert MT4 various indicators to Pine script signal(Trading view indicator)

INFO

I want to convert my existing MT4(.ex4) to Pine script trading view indicator as a trend following signal indicator.

Existing ex4 contains 3 indicators (ichimoku, awesome oscillator and williams %r),

Entry and exit condition will be based on those 3 core indicators.

Trading view signal will not show the 3 core indicators, only buy and sell signals.

The core indicators will also provide condition to change the colors of the candle.

There will be an optional input/features inside the trading view indicators such as:

1. entry, stop loss and target profit

2. support and resistances

3. Volatility range

4. higher timeframe signals

5. re-entry signals

if the work will give us satisfaction, we will definitely give more orders and job.

In depth details of the job will be further discussed during the meeting of the hired developer.

Trading view indicator will look like the file attached.
