To each his own, but in my opinion commissions (within reason) are much less a concern than multiple other factors such as:
- The time it takes to set up orders. This can cause you to miss trade and/or execution opportunities.
- The clarity in setting up orders. One mistake can cost much more than higher commission rates
- Methods in order routing. Some brokers don’t play nice with complex orders in a way that drastically affects execution prices.
- Mobile friendly
- The ability to put in contingent and cascading orders
I’d personally stick with TOS for those reasons with our type of trading.
