I think leading indicators and lagging indicators have their respective advantages and disadvantages. Lagging indicators are indicators that provide signal confirmation after a trend is formed, this provides a late signal so that potential profits may be less than optimal. However, this may reduce false signal bias.
Meanwhile, leading indicators provide signals before a trend is formed, allowing traders to achieve maximum profits because they can enter early when the indicator gives a signal. The weakness is false signals, leading indicators require other indicators for confirmation to reduce analysis bias
