Some days ago i buyed stocks with very high bid ask spread. After 2 hours my trades s cancelled and money back to me There isnst any reason to other side cancel trade because they earn money Brokers monitor clients accounts and do trade bust without costumer request ? or is an automatic process from exchange ?
LMGTFY https://ibkr.info/glossary/746 "A busted trade refers to a situation where an execution occurs and the broker receives the execution message from the exchange. The exchange then realizes some type of error (Pricing, electronic, obvious error, etc) and rules to bust (cancel) the trade. The exchange makes these rulings entirely on their own."
Who is your broker? I need to switch to them. Whenever there is an edge for the other side, my orders are gobbled up at lightspeeds
Each exchange is different. You probably triggered this: https://www.nasdaqtrader.com/Trader.aspx?id=ClearlyErroneous
