同花顺公式编写（The formula of the same flower is written）

同花顺公式编写（The formula of the same flower is written） Notes of the formula function of the same flowers (common parts) Logical functions: 1. Conditional function: evaluate different values according to the conditions. Use: IF (X, A, B) return A IF X is not 0, otherwise return B. For example: (CLOSE OPEN, HIGH, LOW) indicates that the period receives the highest value of the cycle, or returns the lowest value. Reference function: The number of cycles that satisfy the condition: the number of cycles that satisfy the criteria. Usage: COUNT (X, N), counting the number of cycles that satisfy the X condition in the N period, and if N = 0, start with the first valid value. For example, COUNT (CLOSE OPEN, 20) represents the number of cycles in the 20-cycle period of the positive period. 2. The first condition is established to the current cycle count: the first condition of statistics is established to the current period. Use: BARSSINCE (X) : the first time X is not 0 to the present day. For example: BARSSINCE (HIGH 10) represents the current cycle number when the stock price exceeds 10 yuan. 3. The last time the condition was set up to the current cycle number: the last condition was established to the current period. Usage: BARSLAST (X), the last time X was not 0 to the present day. For example, BARSLAST (CLOSE/REF (CLOSE, 1) = 1, 1) represents the current period of the last fluctuation board. 4. Effective cycle count: the total number of cycles. Usage: BARSCOUNT (X), the first valid data to the current number of days. Forward assignment: set the current location to a number of cycles before it is set to 1. Usage: BACKSET (X, N), if X is not 0, set the current position to 1 before the N period. For example, the BACKSET (CLOSE OPEN, 2) is set to 1 for the period and the previous cycle, otherwise it is 0. 6. Summation: summation. Usage: SUM (X, N), counting the SUM of X in the N period, N = 0 starts with the first valid value. For example, SUM (VOL, 5) is set as the daily
