X_1=CLOSEOPEN102; X_2=HIGHCLOSE103; X_3=HIGHREFHIGH1 AND HIGHREFHIGH2; X_4=CLOSE=ZTPRICEREFCLOSE101; X_5=SUMX_4100; XGX_1 AND X_2 AND X_3 AND X_5;

This formula creates a trading signal called XG based on five conditions:

1. X_1: The closing price divided by the opening price is greater than 1.02.
2. X_2: The highest price divided by the closing price is greater than 1.03.
3. X_3: The current highest price is higher than the highest price of the two previous periods.
4. X_4: The closing price is equal to the zero-tolerance price of the previous closing price with a 0.1% tolerance.
5. X_5: The number of times X_4 is true in the last 10 periods is greater than zero.

XG is true if all five conditions are true. This signal can be used to enter long positions in a stock or other security
