Hello, everyone. I am learning/choosing platforms for stock daytrading: Laser, Lightspeed, Sterling Pro and Blackwood Pro. I have a question about these direct access platforms. Which one offers 1st trigger OCO (one cancel other) order entry feature? This feature allows me to input entry price, 1st target price and stop loss price all at once. I was told none of above mentioned platforms offers this important feature. Is it ture and why? Thank you so much for reading and even more for replying!
