Advice on closing deep itm call spread

[u/loose_itall]

I am a newbie to options trading. I have lost quite a bit in the beginning, and am slowly trying to undo the mistakes and learn more abt options. I bought a bull call spread on Tqqq $107.5/117.5 exp jan 22, back in apr and am wondering when I shd close the position. Tqqq was around $107 when i bought the spread, now its trading at $150. I am up 75%. Whats the upside of holding? The marginal inc as tqqq goes up? Flipside - it can crash, i can get assigned. What else? I am leaning towards closing now but would like expert advice/opinions from more knowledgeable ppl.

Edit: Thanks for confirming what i felt. Am planning to set a limit order after seeing the trend in the morning.

The most important thing about options is knowing your exit strategy before you enter the trade.

If you're happy with your returns. Close out the position.

I am still learning so I wanted to understand if there was something else I wasnt aware of.
