crypto-live-trader 0.0.1

???

Intro

• Monitors the entire crypto market kline (candlestick) data, showing 20 symbols only below for illustration
• Other tools

Usage

pip install crypto-monitor

• You can either react to individual symbol updates by defining a callback on_change as shown below
• Or define a task like plot_task below that handles all symbols (x.data) repeatedly

  x.data: Dict[str, np.ndarray]
  x.update_time: Dict[str, int]
  print(x.data["BTCUSDT"], x.update_time["BTCUSDT"])

                f"BTC. my time: {f(timestamp())}, event time: {f(e_time)}, price: {arr[-1, 1]}"
            )

    x = CryptoMonitor()

    x.kline_lim = 10  # Only show 10 time steps for clearer visualization
    x.market = ["SPOT", "MARGIN"][1]
    x.max_num = 20  # Only show 20 symbols for visualization
    x.on_change = on_change

                plot_crypto_data(x.data, id)
                frames.append(Image.open(f"{id}.png").copy())
                assert len(frames) < 150, save_gif(frames, id, fps=5)

    await asyncio.gather(x.watch(), plot_task())


asyncio.run(main())
