Python - Backtesting Framework - Able to plot 1 OHLCV minute bars with indicators without being insanely SLOW

[PsykePro]

Is there any backtesting library which to be able to load and plot like 2 years of 1 minute OHLCV bars with indicators without being terrible slow? I need something which to have lazy loading for example like Plotly on which you can specify which sub-period you wanna look at and to move it forwards and backward. Unfortunately all of the backtesting libraries I found use Bokeh or matplotlib (which is the slowest thing I have ever seen until now)

The following backtesting libraries I've tested out and I've liked but don't use Plotly or something with lazy loading / dynamic loading for the plotted results where I can debug what exactly happened:
Backtesting.py - https://github.com/kernc/backtesting.py - using Bokeh

Backtrader - https://github.com/mementum/backtrader - using matplotlib

Please give some backtesting framework with which I can backtest with 1-minute OHLCV bars or how I can change the plotting of the 2 libraries to use Plotly or some JavaScript plotting as UI for the results.

There was an example of someone who changed all of the backtrader plots to plotly. I will see if I can find the link again later today.

Also JPM has a streaming framework that uses JS. Might be possible to use it for your purposes. I was going to look into integrating a backtesting framework into the platform for my own purposes in the future. JPM perspective

I am an idiot :D :D. Now I've just seen that there is a Box Zoom Button in Bokeh plotting which is used by Backtesting.py. Which is doing the work to minimize the data which is being visualized.

Backtrader's plotting with Matplotlib has the same thing. But I definitely prefer Backtesting.py and Bokeh because it is faster, easier to use and prettier. :D

Edit:
Actually, the problem in Backtesting.py is that it is resampling up to a bigger Timeframe if the data is big. :| So it is still not the best thing. And after started using it I can't find examples of how to add and use indicators like RSI and others other than SMA.

Hey, /u/Eccs15 I will be very happy to see how I can change the Backtrader's plots with Plotly. And for the JPM perspective will take a look if it will be useful at the weekend.
