From multicharts support,
Dear Francesco,

In MultiCharts this value is 0.04 second. If you have any further questions, please do not hesitate to contact us

It is customizable from 100 times each sec to 1 time each 10 sec

The information I sent is for replay purposes.

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?

There is a correlation of factors especially if you are trading tick by tick charts which relate to precision and correct datafeed:

-Latency
-Filtering/Unfiltering
-Timestamping
-Historical Data for backtesting

Fore Elite members, LukeGeniol has made an interesting study on data feeds

Analysis and comparison on different data Feeds and Platforms for Bid/Ask Studies Hi All, 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. Luke. P.s. Is not a simple work, and take …

Has anyone mentioned that this is an awesome thread... :bmt-rocks:

When you create the chart in MultiCharts use the 'merge' option on the instrument tab, then select one instrument (from quotemanger) for historical --- iqfeed if you want --- and then add a 2nd instrument for real-time (from quotemanager). Personally I would just use IQfeed for both in this instance, but you can do it like the above, you just have to maintain two instrument mappings in quotemanager for each symbol -- one for iqfeed, one for zen. Another useful thing would be to have two separate charts of CL for instance, one powered by iqfeed (live) and one zen, so you can see the difference between the two. Mike

works really perfect.
But can anyone explain me the different between in IQfeed:
CLH11
QCLH11

the Plus + is for combined sessions and the #C for adjusted data historical, so far so good.

For Zenfire RT I use: CLH1 => works
For IQFeed I use: CLH11 => works, too but 3-5 ticks different

?

I really, really like MultiCharts for charting. They are clean, crisp, responsive, just lots of small things that make a difference for me I guess. I like how simple it is to add something on/off the chart, temporarily hide it, etc. I like how each chart can be driven by its own data source. Too many things to list in one post, just read the whole thread That said, if you already own NT7 and it is working for you, then why change to MultiCharts. NT7 has one of the best DOM's in the business. I switched because NT was not working for me. Mike

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?

Thanks

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.

There are several contract options with IQfeed.

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.
