Pending order NOT executing

Hi, my pending orders are not getting executed for stocks. Neither live market orders nor limit orders. HELP!

Your orders have been partially filled since the liquidity & the lack of available shares on the market. You create higher demand than the existing supply on the market. The issue isn’t coming from us, it’s due to small market cap, illiquid stock (it’s almost closing time on LSE) so on and so forth.

I see. Thank you for your explanation.
