Without saying which Day Trading Firm , I saw first hand how once their *Now Alert" hit the wire the gap was met with ferocious selling. Stocks were driven into the ground, almost always lower than their 200 day average for months. Looking at the Chart the strange accumulation before the "Now Alert" was obvious.Some "educators" has an army of students ready to buy anything and the "guru" always have the change to sell to them with huge profits.
