thanks for the input.
can you please elaborate more on this? what kind of stocks where you trading,position size, order type (limit/market, marketable/nonmarketable, at the quote limit/inside the limit...etc)?
also what about the time aspect of order filling? average time to fill a market order vs marketable limit order?
thanks again
I use TOS for everything except executions. Love their playback (OnDemand) feature. It will get very expensive to scale in/out. Listen to Robert.
Really does it take 2 seconds to fill market orders in Futures?No. You should run a test for yourself because it will convince you more than a 2 bits electron stranger in a public forum with plenty of trolls. And besides, my experience & connection might not be the same as yours, right?
Btw TDA claims their market order execution speed is 0.2s after receiving order but my future market order is 2s with 300ms round trip ping.
I trade Futures exclusively, and mostly I use market orders. I use CQG via Tradingview for execution, and even in Asian market hours, its market order execusions are almost instant.Btw TDA claims their market order execution speed is 0.2s after receiving order but my future market order is 2s with 300ms round trip ping.

I should said it's probably around 1-2s but the 2s occurred more often than not to be noticeable. And this experience is limited till the early months of 2017. Once I moved off my trading account, it's no longer a concern to me.
The real major concern at the time was their data feed because it's the origin of all the chained reactions ending at a mouse click event. At first, I noticed their trading sim feed many times about 0.5s ahead of their live data feed. I brought that up in TOS chatroom to see anyone noticing anything different and ended up to prove my case. So I did my due diligence by asking for a CQG demo, running the oil future during EIA report, screen capture videos and voila, CGQ is much faster and much more reliable than TDA's data feed. During those fast time, CQG has a window of about 1min to act while TDA is completely lifeless till you coming back century later. One shot like that takes about 5min to recover and if a couple trains running together, well time to turn off the computers.
Then I realized why TOS time frame is limited to 1min, why they couldn't provide the market depth info for data mining, why those users in the chat room couldn't see what I'd see because I looked at the DOM all the times while trading and they looked at their beautiful charts.
The experience w/ TDA data feed isn't wasted on me though because I realized I have to change my strategies & tactics. That makes me a better trader but the experience dealing with the users in their chat forum is useless. They are too occupied w/ their beautiful charts & wiggle lines.
1) for those of you who have been actively day trading on TOS; have you used market orders at all to get in/out of a stock quick? and how fast did the order fill?( given position size)
2) I am reading alot of complaints about TD and TOS regarding their fill quality and price improvement. Does TOS typically fill at bid/ask midpoint or are they continuously hitting the limits.....or even worse exceeding them?
