Mine looked pretty much exactly like this. I allso had that huge div. during globex hours.

I use OEC as datafeed.

What data feed are you using? Check out my chart for the comparison... Specifically how my CD doesn't show the first divergence you had annotated. I wonder which of our CD's are wrong. I'm using Investor RT.

Much to my dismay, it seems you are correct. I downloaded and refreshed the intraday data for that period and came up with this.

I posted a question on the Sierra charts support board so will let you know the outcome. I also use OEC data.

Rainman....great work!

You should talk to OEC and make sure they do not "throttle" or "bundle" data.....like IB's "snapshot" data that may cause problems with delta computations.

I hate to ask for another chart........................ but can you show where you see this 924-927 inventory. I must be overlooking something, because I see a verrrrry tiny held inventory at those levels. Not anything that seems worth deeming important.
More...
This should help see why the return to 927's was a perfect opportunity to SELL............

The chart should also show why I was taking intraday sell signals off the price rotations each time up to the 924 area. After several price rotations just below the delta zone, we had one decent pullback to the 910 area. Buyers took back control off the 910's with very positive delta (buying conviction) as price made a charge to 927's again. Price did finally trade through 927's but with LOWER cumulative delta.....this was the PERFECT area to take SELL signals. :)

A suggestion: What we need for index traders is a chat room. You should consider setting one up. CFFerret started a seperate chat room but some clown stocktrader that throws darts and blows up twice a month stole the chat room and moved it to his kiddie-time website.

I think it would be a good chat room for sure because experienced traders are willing to share and not have plans to "USE" others for a paid chat etc.

I think that's an example of what fearless9 was posting about, and he says that the source of many/all of these "discrepancies" is the CME GLOBEX itself. Some days there are more data discrepancies between data vendors than other days, some services "scrub" data for "bad ticks" realtime, some other services (including the CME apparently) scrub data at the end of sessions.

Not detracting from the use of volume or delta or CD, but something to keep in consideration for reliability of inputs.

Another thing I found particularly interesting is the HUGE discrepancy between the two methods for Delta and/or CD calculation (see I-RT site) (i.e. UP/DOWN tic Vs BID/ASK delta). In a cumulative indicator like CD, these differences seem to accumulate greatly over time, painting quite a different picture in one method versus the other.
