What does 1 mean?

This is a Counter trend strategy.

Once a trend is established, sooner or later, it is going to undergo a pull back or trend reversal.   The Number 1 on the Heatmap and Email alerts indicates that the first major support/resistance has been broken for a MAJOR PULL BACK to start to occur.

Profits are limited since this is counter trend.

For people that are familiar with Ichimoku, the major support/resistance is the Kijun Sen indicator
