When I do the comparsion of a native 10 min chart and the 3 min chart with the expanded 10 min StochD they are both using the same values for StochD(15, 3, 3). I'm also only comparing when the 10 min chart and the 3 min chart should be equal, i.e at 10 min time frames. So at the 10 min bar at 1:20 for the StochD it should match up with the 1:27 bar of the expanded 10 Min StochD on the 3 min chart. It doesn't.
When I compare the 10 min chart to a 2 min based chart with the 10 min expanded StochD I get the same values at the last bar before a 10 min close. For example, at the time 2:00 on the 10 min chart the StochD is the same value at time 2:08 on the 2 min chart, as expected. For this to work, all data must be derived from the 1 min bar and if done correctly you should be able to get it to match up. Your not trying to divide the 10 min bar into the 3 min bar, you are having to calcuate every 10 min and 3 min bar based on the 3 min timeframe. I have just completed this for my own trading program that is working with IB's API but I wanted to see this charted on Amibroker on one chart. This also works correctly on Esignal but I don't want to use the data from them since they charge extra for some futures and forex data. I was hoping that I was doing something wrong but I can't see anything yet.
