TLT in play again as it has levelled the last 4 days. The next key is upward momentum.  This occurs when VIX is GHA and SPY turns RHA in the lead up to the fed meeting (this is key).

SPY can go below 12dma on PMI day but rebound the following. It seems the second Monday at open provides best clear signal.

OHLC bars show open above the line on Dec 8 and below line at close.

HA shows red at open on Dec 8. So second Monday at open would be best time to buy TLT.
