gemini-python VS ccxt

It requires the gemini-python module, which I found did not yet implement the wrap_order endpoint, so I fiddled with the code and called the API directly:

I'm using a Python API (https://github.com/mtusman/gemini-python) to access the Gemini Sandbox. I would like to place some dummy limit buy orders. I notice that when I submit a buy order that is below the market price (ETHUSD was $4430 when I ran this), the result tells me the order was cancelled ...

Yeah exactly I used https://github.com/mtusman/gemini-python. I don't use the library directly though, I copy/pasted the pieces I needed out of it, audited them to make sure it wasn't shady, and made my own local Python script, mostly because of paranoia of trusting someone else's code blindly. This is honestly uneccessary but it makes me feel better.

CCXT

I would sincerely advise you to use a ready to use python library for this like https://github.com/ccxt/ccxt

CCXT has good documentation on what exchanges and API's are supported which is very helpful. https://github.com/ccxt/ccxt/wiki/Exchange-Markets-By-Country

Consider using https://github.com/ccxt/ccxt for crypto exchange interaction, which of course will support Binance too

Check out https://github.com/hummingbot/hummingbot (disclosure: my project). We just added a Binance candles feature where you can construct custom OHLCV candles and TA indicators. You should also check out https://github.com/ccxt/ccxt which has broader exchange support but less order book data management than Hummingbot.

Or if you stick to JavaScript and willing to learn the programming part, then https://github.com/ccxt/ccxt (which is now merged with CCXT Pro but still for free).

Ccxt works great for me and it's free and open-source. You can connect and execute on multiple exchanges. It works with Javascript, Python and PHP.

if you're going crypto, try CCXT https://github.com/ccxt/ccxt

Essentially, to create an automated trading system using TradingView strategies, you would need to acquire the signal using webhooks. Once you acquire the signal, you can use whatever data send with it to manage orders, using the API of your broker. Usually, there are SDKs available to make this process easier. For crypto, one of the most well known SDKs is called CCXT. There are also some made for traditional brokers too. It is a simple process but it does take some experience with programming systems to set up.
