Ok what BIG1 is saying is that if your trade decisions are based on the bid/ask data coming from IB, those decisions would be different than if the data were coming from IQFeed. That's correct, because the IB bid/ask data is aggregated while IQ's data is tick.
But what Jerry is saying is that it if your trading strategy is sensitive to the correct up-to-date bid/ask NBBO data, then it is better to use IQFeed. There is no advantage to using IB's data while trading at IB because IB's fills are not based on the data IB sends to you through its API. They are based on NBBO and other factors, which are not related to the bid/ask or trade data that IB sends out in its API.
I am a bit fresher this morning. Had eye surgery, have slight double vision and my patience is thin. I apologize to Jerry for my tone, I realize he is taking time from his life to comment to help. I am just frustrated that I can't simply turn on what I know works and begin trading. Instead I am under the hood tinkering with crap that makes no sense in the real world and yet I know better because this is the real world. Better than when I started with System Writer, but still not perfect.
I believe that if I create a 5 point chart or 50 tick chart using ASK data for data1, BID data for data2 using IQ I will get a different number of bars and therefore different entrance and exist signals, when using limit orders, then using IB. So if in one instance in the course of the day I have 500 bars with one, if I have 200 bars with the other, there is going to be a difference. Prior to this discussion, I would have expected charts being created using trade data to be the same.
My many years of doing this tells me that if one is going to have a high trading frequency for tiny profits, differences can cause a train wreak. Having said that, I have no idea if it will work or not as I have found out one must verify with live trading to get the data, learn, adjust if possible and move on to the next test.
First I am going to create new charts with 1 bar back so that the charts will build from the live stream. I will be building separate 1 tick bid, ask and trade charts using IB and IQ data. I will build a 1 tick TS chart using trade. At the end of the day I will get a total count, but may end it early if it is very clear.
Next today while the market is closed, I will build both 5 point and 50 tick charts using IB BID and ASK data as well as a separate chart using only last. I will do the same for IQ and finally just a last for TS.
Once the charts have enough bars built I will be in a position to trade IB or IQ live which I will do to see what issues if any surface. I will compare the chart built using TS data in MC, to the TS chart I will trade live using TS.
