Hi Jim. While we don't know exactly what you want to do it is nonetheless certain that it can be done reasonably with RE. This forum can probably be most helpful if we take things a step at a time. It will be more efficient if we help clear up details at each step of development.
- C# is probably the dominate language used. How much experience do you have with it?
- Have you created a watchlist? To start with I would keep it to about a dozen symbols.
- Let's assume an EOD strategy to start with.
- Have you downloaded a few months of historical data from Yahoo? That must be kept up to date each day.
- The manual, particularly the part about "System Strategy Architecture", is going to be quite helpful.
- Look on the RE website under Community > Trading Systems for examples. For example, "Simple Trading System".
Does this get you started?
