I'm trying to create a simple exploration that looks for situations where +DI crosses above -DI; I have tried different versions of the formula, however when I run the exploration on my database of over 600 stocks, I usually get a report of about 20 stocks out of which no more than 7 results are correct (i.e. +DI crosses above –DI); the rest of the report consists of stocks with no crossover whatsoever, or with crossovers that happened a few periods back. I’m currently using MS version 8.01. I'm not sure if the problem is with the software or with the formulas. I have tried the following formulas and I get similar results: 1 – Ref(PDI(14)<MDI(14),-1) AND PDI(14)>=MDI(14) 2 – Cross(PDI(14), MDI(14)) 3 – DIRECT:=PDI(14)>MDI(14); DIRECT AND Ref(DIRECT,-1)=0 Any suggestions would be appreciated

Hi, The second formula is the best one to use. All your formulas are actually correct. The problem is most likely that your explorations are using a different amount of data than your charts. Answer this question : How many periods do you usually look at on a chart? Now go to tools the explorer, click on options and make sure you do not have "Load Minimum record" selected but rather " Load X Records" X being the answer to the previous question. Hope this helps.

Hi Patrick, Thank you so much for your help. You were right; the Data Loading in Explorer Options was set to "Load Minimum Records". I changed that to "Load 1300 Records" and that solved the problem. You've been very kind. Thanks again.
