About the risks of seasonality strategies

Seasonality strategies are risky because price action anomalies may disappear at any time.

These strategies are only good for experienced traders who know how to manage risk and are willing to take on big risks.

When using a profitable seasonality strategy, inexperienced traders may lose money because they are afraid to act on signals that are risky at first but pay off in the long run.
