Unisearch does not allow use of DPO Crossover above / below zero as search parameter when using Industry / Sector Price. Protrader parameter is not available in the operator column. My research suggests if you buy top 3 stocks within the industry when Industry DPO crosses above zero, you could easily pocket 12 to 15 percent profit in a month. Availability of DPO in Operator Column for Industry / Sector search would be very helpful.
