I'm trying some basic inputs to get started in machine learning and finance. I am using the MACD and RSI as predictors in a classification model. I want to eliminate look-ahead bias.
When the MACD (or any other vector-input indicator) is calculated based on a vector of prices, does it include the price of its corresponding index in the calculation?
For example, if my input is a series of close prices, does the MACD calculated for 21 April include the close price of 21 April? Obviously, you wouldn't have the close price of the day you're trying to predict. Can I use the corresponding MACD vector, or will I need to backshift the results by one?
