MyTT Documentation

You can install MyTT using standard pip or by manually including the source file in your project.

Option 1: Manual inclusion (Recommended for lightweight use) Copy MyTT.py directly into your project directory and use from MyTT import * to access all functions.

Option 2: Standard installation

pip install MyTT

When translating TongdaXun formulas to Python using MyTT, note the following syntax changes:

1. Assignment: Use = instead of :=.
2. Logical AND: Use & instead of AND.
3. Logical OR: Use | instead of OR.

Examples:

• TongdaXun: VAR1:=(C>REF(C,1) AND C>REF(C,2)); Python: VAR1 = ((CLOSE > REF(CLOSE, 1)) & (CLOSE > REF(CLOSE, 2)));

• TongdaXun: 收盘价在10日均线上 且10日均线在20日均线上 Python: (CLOSE > MA(CLOSE, 10)) & (MA(CLOSE, 10) > MA(CLOSE, 20))

• TongdaXun: 收阳线 或 收盘价大于昨收 Python: (CLOSE > OPEN) | (CLOSE > REF(CLOSE, 1))

MyTT is a pure Python implementation of technical indicators compatible with TongdaXun and Flush (同花顺) syntax. It uses numpy and pandas for high performance and does not require ta-lib.

Most functions accept sequences (like pandas Series or numpy arrays) and return sequences. You can pass df.close.values or even a list to the functions.

You can define complex indicators by combining MyTT utility functions. Below are common implementations:

def MACD(CLOSE, SHORT=12, LONG=26, M=9):
    DIF = EMA(CLOSE, SHORT) - EMA(CLOSE, LONG)
    DEA = EMA(DIF, M)
    MACD = (DIF - DEA) * 2
    return DIF, DEA, MACD

def KDJ(CLOSE, HIGH, LOW, N=9, M1=3, M2=3):
    RSV = (CLOSE - LLV(LOW, N)) / (HHV(HIGH, N) - LLV(LOW, N)) * 100
    K = EMA(RSV, (M1 * 2 - 1))
    D = EMA(K, (M2 * 2 - 1))
    J = K * 3 - D * 2
    return K, D, J

def BOLL(CLOSE, N=20, P=2):
    MID = MA(CLOSE, N)
    UPPER = MID + STD(CLOSE, N) * P
    LOWER = MID - STD(CLOSE, N) * P
    return UPPER, MID, LOWER
