This code snippet demonstrates how to implement a screener using both the Stochastic Oscillator and MACD (Moving Average Convergence Divergence) indicators across multiple timeframes (weekly, daily, 4-hour, and 1-hour) in the ProBuilder language. The screener evaluates whether both indicators are moving upwards, downwards, or are neutral, and assigns a specific code for each scenario and timeframe.

// Constants (can be used throughout TF's with the same name)
Stoc1 = 4 //4
Stoc2 = 4 //4

Macd3 = 9 //9

// Variables for each timeframe: W = weekly, D = Daily, 4 = 4-hour, 1 = 1-hour
// Weekly Timeframe

MacdDNW = MacdValW < MacdValW[1]

    xW = 1000

SCREENER[Result] (Result AS "wd41")

Explanation of the Code:

• Constants and Variables: The code starts by defining constants for the Stochastic and MACD parameters, which are reused across different timeframes. Variables specific to each timeframe are also defined.
• Timeframe-specific Calculations: For each timeframe (weekly, daily, 4-hour, 1-hour), the Stochastic and MACD values are calculated. The code checks if these indicators are trending upwards or downwards by comparing current values to their previous states or averages.
• Decision Logic: Based on the direction of the indicators, a specific code (e.g., 1000 for weekly upwards) is assigned. This helps in identifying the trend direction across multiple timeframes.
• Result Combination and Screening: The results from all timeframes are summed up and passed to a screener function, which can be used to filter instruments based on these combined trend indicators.
