Create a chart with only one data source at a time first. Pick eSignal or OEC. Which one is the bad one?

Once you find which one is bad, load QuoteManager and go to that symbol - make sure you pick the instrument driven by the "bad" feed. Then compare the "good" feed and "bad" feed instrument settings, paying attention to the tick size setting. One is simply wrong.

Hi Mike,

I did exactly what you said, as well as having multicharts support log in and try and fix it but both feeds are actually good but the price comes in different for each pair for 6E, 6a etc...

They said that i would need to find a feed that has the same price coming in otherwise you cant merge the data together.

Due to this I think the merging is pointless.

Are you successfully able to merge your velocity live account with your current data feed on all products?

Thanks

I see now. IQFeed for example uses FXCM feed pricing, which is what you will see in the world of futures trading on currencies like the EUR/USD (6E). So execution prices at your broker (TT, Rithmic, CQG, etc) will match feed price of IQFeed.

But in the primary foreign exchange market, forex spot currencies, there is no universal price. Each bank/broker is different, so you will see some price discrepancy of a few ticks. Like right now I think the difference between an MB Trading price on the euro and the IQFeed price on the euro is about 10-15 ticks. This will stay roughly the same over the course of a contract, but during rollover may change slightly.

Mike

OEC use xxx.xx price format, eSignal uses x.xxxx.
Open your OEC trader and see.

That's most likely the problem here...

I know MC are working on a feature where you can scale different price formats when mapping/merging symbols.

You are absolutely right this is the problem. Multicharts needs a multiplier in there so we can multiply any feed we decide to use in order to match eatch product if needs, ultimately so we can merge the data and backtest and trade a strategy off of it. Otherwise this is not possible.

OK that makes sense too. I see it with TT via MC as well, TT doesn't use decimals at all in their feed. All other applications let you use a multiplier, but not MC for whatever reason. Hopefully they add the (required) 'feature' soon.

Make sure you have an open Project Management request for this on their end.

Mike, I thought you merged the data from TT and IQfeed. Are you not merging the data together?
