Frequently Asked Questions

ta.macd() computes the MACD indicator: typically the difference between fast and slow EMAs of source (MACD line), an EMA of that line (signal), and their difference (histogram). It helps assess trend and momentum.

A MACD line crossing above the signal line is often read as bullish momentum; crossing below as bearish. Histogram expansion or contraction can reinforce whether momentum is strengthening or fading. Always combine with context and risk management.

A common default is fast 12, slow 26, signal 9 on close. These are conventions, not universal truths—tune lengths to your timeframe and instrument.
