In short, I've finished the coding and am testing it now. I've tested that everything adds/edits/deletes, and that doing so through the new wizards produces the same results as the corresponding windows. That kind of thing is looking solid.
Next is ensuring that backtesting still spits out the correct results. And trying out the new backtesting functionality which lets you click a button and it puts all the indicators you used, and entry and exit points on the chart.
After that is testing auto-trading, which is fairly important :-)
Sorry for the delay. I was working on this really solidly for a while there and needed a bit of a break. But it's again become a habit to sit down and work on this. I was in the habit of sitting down and letting the Internet take me on learning (procrastinating?) adventures. E.g. how to make a sponge cake --> how to make various other cakes --> cooking in general --> edible balcony garden --> Autopot --> permaculture. That chain took quite a few days to finish. There were many others. So many websites. So many Youtube videos :-)
