I only have one question: Will it make a lower low???
As if it can not, 4H EWO divergence will work out, and next spike above 17,21 will be succesful.
Strategy: in case of a confirmed higher low on 4H, buy 0,5 unit at 16,45 and 1 more unit above 17,21
Key is 17,21! (daily Kijun + 4H Kumo and 100WMA)
