COMMENT "CHART"
Build a free live trading chart on 4 exchanges
One free tool called ccxt, plus Claude Code, builds you a live price chart on your own computer, pulling four exchanges at once, for zero dollars. No code, one sentence.
01Quick steps
- 1Free tool: github.com/ccxt/ccxt (open source, connects to 100+ exchanges).
- 2Open Claude Code and paste one sentence (below).
- 3Let it install ccxt and write the chart, then run it. You get a live chart showing the same coin on four exchanges at once.
02Your ready to use prompt
Use ccxt to build me a live price chart in my terminal that shows Bitcoin on Binance, OKX, Bybit and Coinbase at the same time, updating every second. Keep it simple and tell me exactly how to run it.
03Full tutorial
Download Claude Code and open it, and make sure Python is installed too (it is free from python.org).
Open github.com/ccxt/ccxt in your browser just to see it is real and free; you never download it by hand, Claude Code installs it for you.
In Claude Code, paste the one sentence below (the script) that describes the chart you want.
When Claude Code asks to run the install command for ccxt, say yes so it adds the tool for you.
Let it write the small program that pulls Bitcoin's price from Binance, OKX, Bybit and Coinbase at the same time.
Run it using the exact command Claude Code gives you; a live chart opens showing the same coin on all four exchanges, updating every second.
When one exchange shows the coin cheaper than another, that gap is the thing pros watch.
Change the coin any time by telling Claude Code 'swap Bitcoin for Ethereum' (or any coin), and it edits the program for you, no code typing.
Save the file so you can reopen it and run the same command whenever you want the chart back.
ccxt is a free, open-source tool that already knows how to talk to over a hundred crypto exchanges. You don't build that connection yourself, ccxt hands it to you.
You don't write code. You describe the chart you want in one plain sentence and Claude Code installs ccxt, writes the program, and tells you how to run it.
Seeing the same coin on four exchanges side by side shows you where it's cheaper or pricier. That gap is something pros watch, and now you can too, for nothing.
This is a free tool build, not trading advice. The useful part is seeing the same coin on four exchanges at once, so you can spot when it's cheaper on one than another.
