Want to watch the BTC bull run whilst you work?
This simple rust application for OSX streams theBTC/USDT price from Binance, and displays it in the OSX menu bar. It features a few options:
- portfolio mode
- rounding / displaying with decimals
- averaging the last N seconds
This btc price ticker was built for high frequency (live / realtime) updates, in a way which would minimally impact the system. Currently the price ticker updates up to once every 100ms. You can change this value (at the top of the makefile) by running make uninstall, updating PLUGIN_TARGET and doing make install.
The memory footprint of the server is quite low, about 4 MiBs. CPU usage of the server is minimal on the test hardware, less than 1% (Mac M2 pro max). Swiftbar on the other hand seems higher, about 3% CPU usage on average.
It is composed of a client, which swiftbar runs every 100ms, and a long-running server that streams price data from Binance, and makes it available via a unix socket.
The Binance websocket reconnects after disconnections. Data usage is approximately 250MiB per day (assuming 24h, so likely less than half of that).
After some time, there seems to be quite a few client process running simultanously. Once can only assume Swiftbar doesn't stop processes as expected. Please check for updates for once this issue is resolved.
$ git clone https://github.com/lightingorb/orb-price-ticker.git && cd orb-price-ticker/
$ brew install swiftbar
You'll need to build this application using cargo, here are some brief commands to install cargo in OSX. If these don't work for you, please research how to set up cargo & rust for OSX.
$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
$ export PATH="$HOME/.cargo/bin:$PATH"
$ rustc --version
$ cargo --version
$ make
$ make install
