There is a 1 to 2 pip higher difference on MC quote compare to the one I receive on Excel
I'm not using the free version, but the fully paid one. I would not be surprise to see a difference with the free MC version, but not with the fully paid licence
I'm not again MC to have a special arrangement with IB ( "Bien au contraire"). Just that if it is true, then I was not aware of that.
Let's assume for a moment this alternative hypothesis would be true - so that the IB price in MultiCharts is 1 pip off, so that the extra slippage goes into the pocket of MultiCharts.
If that's true, we must give MultiCharts credit for being very powerful - not only do they have struck an agreement with Interactive Brokers, they've also convinced MB Trading to join them, and even the CME Group has joined their dark side:
As you can see in the screenshot, taken just now (timezone UTC/GMT +1), all instruments had the same bid price. So if the IB price would be off with one pip, the 6E price and the MB Trading price would also have to be 'manipulated'.
Now, what would be a more logical explanation?
a) MultiCharts has struck an super secret agreement with Interactive Brokers, MB Trading, and the CME Group that hasn't been uncovered - until now,
b) There's a bug in your Excel sheet or in the way that the data get delivered into Excel.
