OptionsCanvas

Stop getting your stops hunted. SL/TP never touch your broker - only fires when the underlying actually breaches your level. And skip the options chain: drag your levels on the chart, we auto-pick the strike + DTE + contracts. The first open-source platform that does both. Maintained by calesthio on GitHub, where it has earned 56 stars from the community.

It's actively developed around 0dte, algorithmic-trading, alpaca, and is a solid reference for anyone building with these tools.
