📊 Controtto

A self-hosted, P&L tracker made with Go, HTMX and no JavaScript. Controtto, keeps track of your transaction saving it in a sqlite file, and returns all sorts of calculations including:

• Avg. Buy price
• Current asset value
• Transaction history
• Import / Export transaction (see sample)
• Profit & Loss

In order to fetch the price of an asset, Controtto relies on mainly 4 APIs (see code).

• Binance - Public API, no token needed.
• BingX - Public API, no token needed.
• Alpha Vantage - Stocks, free but short rate limit. (get an token and set CONTROTTO_AVANTAGE_TOKEN)
• Tiingo - Stocks, crypto and Forex. (create account/token and set CONTROTTO_TIINGO_TOKEN)
