What are the best day trading platforms?

IBKR without a doubt for the low fees involved.

Some might say Tiger but I am a lil hesitant after hearing stories of delayed trades etc.

Interactive Brokers hands down.

1. Literally designed for professional trading

2. Largest broker in the US by daily trading volume

3. Long history (close to 50 years)

4. Low comms (as low as USD 0.35)

5. Spot FX rates

6. Virtually any market you need

7. Crazy number of order types to choose from (Trailing stop, Trailing Market, Limit Stop, Market on Close, the list goes on)

8. Minimal payment for order flow (less than 1% of the orders on IBKR)
