Open Source Trading Platforms
For the uninitiated, the first question will be why do they need to go with an open-source project (OSP) after all? OSP can in no way compete with the support and timely updates of a commercial platform. The answer depends on your needs. A retail commercial platform such as Amibroker on Ninjatrader shall be able to address most of your requirements. But everything has limitations, and because their source code is proprietary, it can be hard to extend their capabilities. This is where people invest time/money to trade with an OSP. I started looking at options with the need to connect Amibroker with Sterling API.
I will be updating this list regularly, please add your comments.
