I don't know what's the thoroughput of services such as IQFeed or Zen-Fire, or how much data would push it to its limit. In other words, at what point does the difference become noticeable?
I wil try here to do an analysis and comparation on different data feeds and platforms to perfom studies involving bid/ask data, like comulative bid/ask difference or delta bars and footprint like.
Thanks Mike! I finally did get it to work, realized I had an old MBDesktop client which was the issue. So far like DT very much but need to play with it. Don't own NT but would happily pay for it however need to see how MC works for me. Not too concerned about DOM as I havent really used it.. might be something to look into but I do really just like chart trading.. either way have some time until I'm back on live..
Out of curiosity one thing that did occur to me and figured someone here might know.. Is there a way in anyone of these platforms to tell it to work off the BID when chart trading? For example, lets say I go short and trail a stop; on the chart as it stands now if the ask hits the price it gets you out so I usually end up putting in the difference manually, however would there be a way for you to tell the software to execute the ask (or buy) on a bid price?
QCLH11 is globex, CLH11 is pit, CLH11+ is obsolete.... it's for the time when pit and globex were not trading side by side. So it only will apply if you're looking at some older charts.
Also of note: Q prefix applies to nymex and comex, in the same way that @ prefix applies to cme and cbot.
The Q means electronic session. Without it you get pit only (not good). If you prefix with +, like +CL, it is combined session. I've briefly looked at #C but personally I've setup QuoteManager to create a custom contract, a continuous contract that rollsover based on volume of the front month.
For MultiCharts you can add a bid/ask dataseries so that your strategy can look to data2 or data3 for the bid and ask. For instruments like CL or ES, it is probably much easier to just add 1 tick of slippage, because it is extremely rare that the spread is more than 1 tick.
You can also tell MultiCharts to only count a trade as executed if price penetrates the price, so a long limit order would require price to go 1 tick 'against' you before it would be counted as filled, and a long profit target would need to trade 1 tick 'beyond' your target to be considered filled. These are options in the strategy menu.
