The "TemaPureTwo" strategy is a trading strategy that uses various technical indicators to generate buy and sell signals. Here's a description of what the strategy does in short terms:
It populates the given DataFrame with several technical indicators, including the Chande Momentum Oscillator (CMO) and the Triple Exponential Moving Average (TEMA). It calculates Bollinger Bands with different standard deviation values (1.0, 2.0, 3.0, and 4.0) using the BBANDS function from the TA (Technical Analysis) library.
The lower, middle, and upper bands are stored in separate columns in the DataFrame.
It determines the buy signal based on two conditions:
The TEMA crosses above the lower Bollinger Band (bb_lowerbandTA1).
The CMO value is greater than -0. If both conditions are met, a value of 1 is assigned to the "buy" column in the DataFrame. It determines the sell signal based on one condition:
The CMO crosses below -25. If the condition is met, a value of 1 is assigned to the "sell" column in the DataFrame. Overall, the strategy aims to capture potential buying opportunities when the TEMA crosses above the lower Bollinger Band and the CMO is positive, and to identify selling opportunities when the CMO crosses below a certain threshold.
