One of my peeves about TWS: For rapid pace daytrading of American-listed stocks (or any other single/few specific exchange style trading, rapid pace) that one extra step of having to specify exchange, etc. on the drop down when you enter a symbol.
One should be able to, in configuration settings, exclude certain exchanges from ever popping up, or alternatively, be able to specify only specific exchanges for when specific symbols are entered.
I.e., in an event, for the time it takes me to quickly enter symbol, and an order for 5 random symbols, I could have done 10-15 symbols and same order in an Anvil style platform.
Anvil: Symbol, Enter, Hotkey.
TWS: Symbol, Enter, Scroll and Select Proper Security, Enter, Hotkey.
Obviously Anvil, etc., and TWS are not meant to be direct competitors, but not being able to configure around this somehow, is annoying.
