PINE SCRIPT to put a button on screen to trigger a manual buy signal.

I am after a PINE SCRIPT developer that can create a BUY button in Tadingview using a strategy/study.

I am a SCALPER so I want to send trades to 3Commas. 3Commas in turn will create a trade based on the BOT parameters in 3Commas.

UseCase:
I will TA analyze the pair using TradingView, let's say BTCUSDT, and when I want to place a trade, I just want to click on the BUY button.
YOUR script, will then assemble the jason file and send it, using the webhook to the URL I provided in the admin side.
The BUY action then sends the jason file to the URL of 3Commas.
3Commas will be configured to consume the jason file and create a transaction on the exchange.

How I would like to use it:
I should be able to configure more than one CryptoPair. Only the applicable BUTTON should be shown on TradingView chart.
Information will be extracted from the alert trigger and sent to the webhook as a jason file.
Attached find a word doc to elaborate.

Feel free to ask me if anything is unclear.

If you can do it, please let me send related projects info?
