Good broker without silly restrictions

what is a good broker without rules like that the equity can not drop below 50% like on ig markets

If you are trading with Margin, the broker will apply a margin call level and stop-out level, you can find some brokers with a stop-out level below 50% but is critical to understand the broker business model.

Thank you for your valuable insight!

Do you know any broker who I can work with low commissions and spreads?
