MFI is generally considered a leading indicator because it incorporates volume, and volume tends to lead price.
The Money Flow Index is a leading technical analysis indicator that measures the strength of capital flow by analyzing an asset's price and trading volume, making it superior for confirming trend strength and spotting volume-driven reversals.
It can also be regarded as a lagging indicator in specific circumstances since it uses historical price and volume data, meaning it cannot immediately signal changes in trend or market reversals.
Most traders treat divergences as the leading signal.
