It is of my opinion that this market has no reason not to rally to .7500
Price has been rejected by the market at the .38% retracement and shortly there after price failed to make new structure lows as would be expected in this predominantly bearish trend, resulting in a nice sequence of higher lows.
The projected .50% retracement is convergent with the extension of .38% retracement leg AND this conveniently meets at a previous structure low.
