It probably depends on the datafeed and /or the interface.
Check with Dynastore that works differently and is probably more accurate now
( there is a cold war between Esignal and TS)
I have never seen this with SP Comstock Xpress feed.

Ditto.
Try to switch to an other interface
Esignal has made some changes that could maybe affect it, but I'm not sure.
Try some database maintenance first, but I cannot understand why a 500 ticks and
5 min chart are not updating at the same time.
Never seent such thing reproted here.
Frankly...
