This ProBuilder code snippet is designed to screen for stocks that are in an uptrend and have formed two consecutive higher troughs, which can be a bullish signal. The code uses a combination of moving averages and the Zigzag indicator to achieve this.

ma = average[100]
up = summation[50](ma>ma[1])=50
zz = zigzag[2](low)
creux = zz>zz[1] and zz[1]ll[1] then
        llh=1
    else
        llh=0
    endif
endif
screener[up and llh]

Explanation of the code:

• ma = average[100]: This line calculates the 100-period moving average of the price.
• up = summation[50](ma>ma[1])=50: Here, the code checks if the moving average has increased over the last 50 periods. The ‘up’ variable will be true if all 50 comparisons are true, indicating a strong uptrend.
• zz = zigzag[2](low): The Zigzag indicator is used with a 2% deviation to identify significant lows (troughs) in the price.
• creux = zz>zz[1] and zz[1]: This condition checks for a trough that is higher than the previous trough, which could indicate a potential reversal or continuation of an uptrend.
• if creux then: If the above condition is true, the following block of code will execute.
• ll=zz[1]: This line stores the value of the previous trough.
• if zz[1]>ll[1] then: This condition checks if the current trough is higher than the last trough.
• llh=1: If the current trough is higher, ‘llh’ is set to 1, indicating two consecutive higher troughs.
• else llh=0: If not, ‘llh’ is set to 0.
• screener[up and llh]: The screener function will return stocks that meet both conditions: being in a strong uptrend and having two consecutive higher troughs.
