Early Warnings: using Trend Shift Indicator divergence.

The attached chart has much of the explanation.

Here are the highlights:

• TSI gives early sell warning via high values (near 170), relative highs, or in rare cases an "x" signal.
  
• Divergence with price is also a key indicator of future action.
  
• Examine the divergence illustrated during the price drop and the (still red) TSI values.
  

I hope this is helpful. Feedback appreciated.
