Hi ThinkOrSwim users. I have read many complains about the lagging/slow data on ToS. I have tried their demo and can see that its a little slower than my IB. Especially during fast movement in the market. I was wondering if its the same on a real account? 1 or 2 tick bad fill can cost a lot in the end so perhaps its better to use another software with IQ feed. Hope to hear some feedback.
