This flag consolidation setup stock screener will help you find with ease good potential entry points for long setup for stocks which have made a recent Volume spike and a sharp move. 

Here is how it has been formulated: 

1. there was a breakout of Volume over its 20 periods average in the last 10 days
2. the squared percentage of the price Close minus the 7 periods average made a breakout over its 200 periods average + 80% of its standard deviation
3. the SMA 7 is over the SMA 200 and price Close is over the SMA 200
4. the current candlestick High is below the highest high of the last 3 periods

c1 = summation[10](volume crosses over average[20](volume))>0
a = summation[3](close-average[7]/average[7])
diff = square(a-a[1])
avg = average[200](diff)+std[200](diff)*.8
c2 = summation[10](diff crosses over avg)>0
c3 = average[7]>average[200] and close>average[200]
c4 = high<highest[3](high)

c = c1 and c2 and c3 and c4
