This ProBuilder code snippet is designed to detect when two specific moving averages, the Kijun Sen and a 20-period simple moving average (MA20), are within a specified percentage proximity of each other. Additionally, it checks if the last two closing prices are above both these moving averages.

prox = 3 //proximité en pourcentage
// -------------
ikijun=KijunSen[9,26,52]
mm20=average[20]
ratio = mm20/ikijun
percent = abs(1-ratio)*100
test = percent<=prox
below = summation[2](close>ikijun and close>mm20)=2
screener[test and below](percent as "% prox")

Explanation of the Code:

• Variable Initialization: The variable prox is set to 3, which represents the proximity threshold in percentage.
• Calculating Moving Averages: ikijun calculates the Kijun Sen using its typical parameters (9, 26, 52), and mm20 calculates the simple moving average over the last 20 periods.
• Ratio and Percentage Calculation: The ratio of MA20 to Kijun Sen is computed, and percent calculates the absolute percentage difference between these two values.
• Proximity Test: The test variable checks if the calculated percentage difference is less than or equal to the proximity threshold.
• Price Position Check: The below variable uses the summation function to ensure that the last two closing prices are above both the Kijun Sen and MA20.
• Screener Output: The screener function outputs cases where both the proximity condition (test) and the price position condition (below) are true, displaying the percentage proximity.

This snippet is useful for traders or analysts who want to monitor the convergence or divergence of these two key indicators, potentially signaling changes in market trends.
