We here at TAAPI.IO are very pro open-source projects, and part of your subscription money goes to the open-source project that we utilize. However, this is much more a service than it is a development project. We’re not inventing new indicators, we’re merely just a “middleman” connecting implementations for the most popular indicators with the crypto exchanges (and yes, we will get to the stock market as well). And this requires a lot of server power. Imagine 200 indicators available for our current 10 supported exchanges with 400 markets on average, that gives you a little short of a million indicator calculations available to you. The whole reason for starting up this project is to remove the hassle of implementing the indicators, so that you can focus on making your trading and bot implementation faster and easier.
