CPU Usage with IB Data Feed

[NinjaTrader_JoshP]

Thank you. Have forwarded to development.

For your own pivot indicators I suggest you re-base them off of the new Pivots indicator after the next beta version.

Unfortunately I still see 25% CPU max with the IB data feed with B16.
Plotting ES, NQ, YM, TF, 6E and TF using one minute charts; there are 4 pnF charts using 1 minute data. All indicators are calculateOnBarClose = true.

Any Update?

aviat72,

We have already resolved the issue we isolated from Harry's workspaces awhile ago.

Please send in your workspaces as well.

Just to close the loop on these.

The latest NT Betas are working fine with IB, and the original problem in the first post are gone.

Some of my problems were due to an indicator (a modified system indicator) which was doing too many calculations in the custom Plot function.

The NT pivots indicator originally caused a CPU problem by performing calculations within the custom plot. I had used this code for the SessionPivots and FibCluster indicator. The latest version of the NT pivots indicator has addressed this problem, and the current version of the SessionPivots also uses the modified code to reduce CPU load. Still need to check the FibCluster indicator.

NT6.5 custom plots used less CPU, as they only needed to provide for equidistant bar plotting, whereas NT 7 has multi-dataseries capabilities, slowing down the plotting. CPU load is reduced for SessionPivots V22 and later / FibCluster V14 and later.
