I'm not sure where this thread goes and I apologize in advance if it's in the wrong section. I have a set of historical market data going back to the year 1900. Data for stock market indices, commodities, financials, etc. However, I'm not sure how to use this data in order to create a chart. I've tried with NinjaTrader with no luck. The data comes in Excel files, by the way. Would someone be willing to look over the data files and suggest what I could potentially do?
