Elliptic Curve Integrated Encryption Scheme for secp256k1 might work for you. It is based on a key exchange you need the private key of one and the public key of another. This would work with Ethereum address keys (and Bitcoin). This makes a 256bit key which can be used for AES encryption for example. Checkout this implementation + the readme is a good explainer: https://github.com/ecies/py

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.
