This became a requirement after deploying `binance` feeds which hit trade / book quote rates in the 500-1k Hz instantaneous rate range (with high burstiness obvs) pretty often. The original...
IB has [historical bar pacing restraints](https://interactivebrokers.github.io/tws-api/historical_limitations.html) which are pretty annoying if you're looking to load up on high frequency data (like we do 🏄🏼). The main limitation for our purposes...
Panning is broken after https://github.com/pyqtgraph/pyqtgraph/commit/61f067bf7c908c8a8f9f0de5cdc1a95c444bf722. Haven't figured out what does it yet but pinning to the commit prior at least gets us testing the new `QPolygonF` optimization attempts from https://github.com/pyqtgraph/pyqtgraph/pull/1796....
Though #157 seem to fix most lo vs. hi DPI issues, where spawning a UI will configure sizing to *where* (i.e. the dpi of the source display) it was started,...

After #205, we actually have all the machinery to load account names from backends with the table-section synax: ```toml [accounts.ib] ira = 'U3566665' [accounts.binance] margin = '3459039485' ``` We basically...
With #212 comes some nifty features like task broadcasting (from `tractor`) and quote stream *pausability* for keeping tasks switches in Qt apps as low as possible for performance. I'm thinking...
We have a *very naive* quote rate limiting [helper func `uniform_rate_send()`](https://github.com/pikers/piker/blob/master/piker/data/_sampling.py#L258) which we can probably make slightly better by using a leaky/token bucket algo. njs' gists just so happen to...
For `piker`, python is glue and a great interactive lang for getting things done in a readable maintainable way. Using it does not preclude using faster (compiled) langs for processing....
Since #164, we've had multi-feed streaming for charts but it would sure be handy if you would get a overall *status* of a particular provider connection possibly in the new...
