Hi, I'm writing a C++ program that has a few technical analysis indicators in (EMA, MACD, ADX, Stochastic K and Stochastic D). I was wondering if anybody has a set of data that I could use to test that my formulae are generating the correct values, before I utilise them in my application? Anything would be great, i.e. just some S&P500 data with the corresponding ADX, S:K, S, EMA and MACD data over a certain time period. All I need to know are the periods that you've used the indicators for (i.e. 9-day EMA for instance). Thanks that guys, much appreciated. Mike.
