Bleh, just ran into this issue oddly (though i swear this was working before?!?) More or less summarized best in this forum issue: https://groups.io/g/insync/topic/7424102?20,0,0,0::,,,0,0,0,7424102 Basically if you have a local...

Another eventually relevant feature request is [UDS support in `tractor`](https://github.com/goodboy/tractor/issues/109).

we need to test the old behavior (reversion of https://github.com/pikers/piker/commit/9c185220305ec4f7c17e2baa9822ac3b54e83ca4) against the patch in https://github.com/pyqtgraph/pyqtgraph/pull/1461.

Oh, also we've removed the `np.append()` stuff and now have a new shared mem subsystem coming in #112, so all that discussion can be marked solved.

Good news. Got a massive massive latency fix with large(r) data sets by using `pyqtgraph`s [`functions.arrayToQPath()`](https://github.com/pyqtgraph/pyqtgraph/blob/master/pyqtgraph/functions.py#L1441) to generate a `QPainterPath` with gaps in it to make up bars graphics. Turns...

Tried out `trendspider` for the free trial; it's definitely a neat idea. Big quiffs include: - no scripting language for backtesting - super laggy and slow (can barely view any...
