At 1678, wave 5 has achieved its first objective of equating wave 1, both in respect of time (it was to achieve on 15 May) and magnitude. It has also perfectly touched its first channel line. So there are 3 important confluences.
However, wave 5, for it to be termed so, must achieve progress, to finish beyond the top of wave 3 (1720), targetting 1788 (1764 primary wave target) as first target, therefore it normally should be wave (i) of progressing wave 5. If this wave retraces fully, i.e. below 1621, then either it would be continuation of wave 4 or end of movement (end, only if goes below 1584). The current wave, since it achieved its first target, should see normal retracement to 1644 (maybe more, but not below 1621).
Important to see how further this wave unfolds. If it goes up again, making wave (iii) of wave 5, after its retracement as mentioned above, then original targets would hold true.
For now, moving up the stop loss to 1620, from earlier stated 1585. Not willing to continue in long position if it continues to remain protracted and frustating wave (iv).
