I want to automate tradingview with capitalise.ai - pine-script-v5

Question

I'm a beginner, but I made a script from existing scripts.
But unfortunately it doesn't work. 😦
I want to automate tradingview with capitalise.ai.
Now I get 2 signals for each candle, but I only want to get 1 signal if it is at a SellSignal or if it is at a BuySignal.
Can this be solved?
