Target update for Double RePo on SP500

This is another approach of determining FInal target for DRPO signal. Its actually more accurate than 50% retracement cause it leaves less room for interpretation.
I have just applied it myself the first time on this chart and think its interesting to see that the OP has held the market two times already. Still until we get a monthly close above 2000level the Double Repo stays valid and the target at 1600 should be reached...
Possible is much lower as you can see back in 2008 when the last DRPO was traded in this chart(note the nice reaction to the completion point there too)
