Hi Richard, thanks for the reply. No, I haven't built an expert yet, only toyed with the built-ins. I remembered it plotted arrows after I had already posted. Guess it's time to build a "trendline expert!"
I'm not sure the formula language is rich enough to write trendline code. If you throw out all the canned indicator calls, there's not much left of their formula language. wonder if you can call external functions or link in a library of externally developed C-functions. I dont really want to have to export the data array, process it, then bring it back in. I never realized how many decisions the old brain makes on the fly when drawing trendlines. Writing the code for this is pretty involved. It's more like a state machine with many, many states, and dependencies on a variable number of past states. It has to work with a huge number of combinations of possible consecutive h-l-c patterns and relative offsets. Hmmm....maybe this is why there aren't any automatic trendline tools built in to metastock. Parabolic SAR is probably the closest, but it's not the same as my trendline rules (or maybe I don't have as complete a set of rules as I thought!).
