Hi,
IB is my main broker, but I believe in having a backup broker or 2 for safety. Platform and execution reliability in volatile markets and cost are most important to me. I trade both ES and SPY. Tradestation’s $100/month does apply to me, because I don’t trade enough or have the $100k+ balance. TOS is an option, but I’ve heard horror stories about reliability in volatile markets. Could anyone make some recommendations? Thank you!
