Partial close in TradingView based on Alert

Hi there,

Does anyone know how to automate a partial close in TradingView based on price hitting a certain price alert?

Basically, say if I have 2000 units (2 micro lots) and I want to automatically close 1000 (1 micro lot) at a certain price alert and then close the other 1000 units at the next price alert are there any third party software or coding scripts that I can use for this?

My broker is Forex.com.

I've searched the internet for automation based on TradingView alerts but seems to be only available for Crypto exchanges.

Thanks,

Shaye
