If it closes below my dashed short-term line I would expect the market to go sideways for a while (like 6 months) before continuing up.
Long-term I would begin to worry if it actually gets below 14540.
That all being said I wouldn't hang on if it gets below the dashed support line because it could be a year before it makes its way back to 16600.
Now would be a good time to get into the market and set the stop 1% below the dashed support line.
Let me know what you think.
