A CHANGE of background color indicates a trade opportunity :
Cyan background = BUY
Purple background = SELL

The bullish signals seem to be better than the bearish ones.

Based on the "Willy" indicator.
Don't change the parameters unless you fully understand the consequences.

Use with brains and caution :)
