Investopia

I use the Investopia Stock Simulator for trying out my theories. I am the user Acmetrades, and I have been using a DMI to gauge whether the market is trending or channeling, and using the ADX to trade trending, and the MACD for trading channeling markets. So far I've had my ups and downs (a little stock trading humor there).

I use prophet.net's Javacharts for doing my research. Have for a long time, I like them. Their free service is unparalleled, even with its limitations.

Currently also exploring momentum trading, using two long-term EMAs to determine up or down trend, and initiating a trade when both the MACD-histogram and the 13-EMA move in the same direction as the trend. More to follow...
