SC Support,

I am experiencing significant differences for TICK-NYSE and NISS-NYSE between Sierra Charts and other systems. In addition to actual difference in values, the numbers from SC show a different trend through time compared to the other systems.

TICK-NYSE on 3/11 @ 9:45 EST +39 close on SC
TICK-NYSE on 3/11 @ 10:45 EST -179 close on SC

NISS-NYSE on 3/11 @ 9:45 EST +110 close on SC
NISS-NYSE on 3/11 @ 10:45 EST -472 close on SC

1) Is this the result of using a data feed from Interactive Brokers?
2) Would the data be different if I were to pay for the SC feed?
3) If yes to #2, can you please write back with the corresponding numbers so I evaluate?

Many thanks in advance for your help.

1. The data does not come from IB.

2. No.

I'm having the same problem with NYSE NISS stats.. They have been off by about 200 the past 2 days. I use SC datafeed with the corresponding stats. Compred to Wall Strret Journal Numbers. Adv/ Dec aren't right either.
