Hi mcmpick
 
Further to my initial response, the "# Equis - Helper Darvas buy" formula called by the Darvas exploration has 5 PREVs, and the sell formula a couple less. The exploration also has a PREV in column E. You may also be loading an excessive number of records, though I would caution against switching to the "Load Minimum Records" as that could possibly produce invalid results (I have not tested this possibility).
 
By removing all PREVs from the said formulas I have managed to reduce the scan time of 300 securities (1000 bars) from 52 seconds down to 11 seconds. I haven't looked at the other explorations and the related formulas but I suspect that the situation is much the same with them also. I notice that the Darvas system uses the Intellistop formulas and I believe that these also include a PREV, but probably not one that can be removed by alternative MFL coding.

why are the new scans (darvas,stochastic,etc )so painfully slow?
