Boomer pattern
The boomer pattern is a special graphic configuration formed by three bars in sequence, of which the last two are inside the previous one. In practice the first bar encloses the two successive which have minimum and maximum respectively upper and lower than the previous.
Ultimately, after the first bar, the pattern contain two “inside days”, days when the minimum and the maximum grow without exceeding the values of the previous range.
That graphic situation indicates a progressive compression of volatility which normally gives rise to an explosion of significant quantities prices.
This pattern identify a price squeeze consisting of three bars in the sequence having the characteristics described above which is a prelude to a subsequent volatility of explosion. However this pattern of course not allow in any way to predict the direction of the breakout, if not relying on continuation pattern or reversal of technical analysis, such as the triangles that are formed on a maximum or a minimum period of rather than in the middle of a trend in place.
The pattern, results in a triangular shape which can be of a reversal or continuation of the main trend.
In this ProScreener code, an ADX filter is added to know if the instrument is trending (ADX value must be above 25 at least).
I also add a DI+ and DI- comparison (above / below), to find what is the actual trend and give an information of what would be the direction of the triangle breakout : bullish or bearish. This is the sorted column criteria: 1 = potential bullish explosion to come, -1=bearish one).

I created the indicator
//Boomer pattern indicator
c = summation[2](high<high[1] and low>low[1])=2
v = summation[2](volume<volume[1])=2
a = adx[14]>=25
d = DIplus[14]>DIminus[14]
e = DIplus[14]<DIminus[14]
boomerlong = c and v and a and d
boomershort = c and v and a and e
//bullish trend
if boomerlong then
DRAWARROWUP(barindex, low- low*0.003) coloured(0,255,0)
DRAWcandle(open, high, low, close) coloured(0,255,2)
DRAWTEXT("Boomer Long", barindex, high+high*0.03) coloured(255,255,2)
endif
//bearish trend
if boomershort then

return boomerlong or boomershort
Hi Nicolas, your screeners are great thanks heaps! I am just getting used to PRT. Any chance you have some for: Cup and Handle Pattern, High tight flag and (VCP) volatility contraction patterns.....??
