Does anyone else trade options on the ICEEU Market

Hello all, UK based using IBKR.

Started selling options as a way to generate capital gains to use towards my tax free allowance, as my first year doing so I'm opting to keep it a bit more simple and stick to UK stocks.

I've filtered down the stocks that are within my budget, as I'm running CSP and or CC plays with a cash account and also checked the market data for volume and OI and this has left me with the following selection of stocks in the first photo.

This is my section before I start any research into the stocks to work out which ones I want to go for.

Does anyone else trade on the ICEEU market? If so what's your experiences with time taken to fill orders?

I also feel like my section is leaning into financial sector, would it be better to spend more time researching a few sectors or focus more on a general understanding of all the sections.

Kind regards,
