ETH bull at medium term count

Despite the bullish medium term count I expect some retracement at this point.
At short term I have doubts if wave iv of iii of iii (orange count) labelling a triangle or a simple zigzag:
a) If wave iv of iii of iii made a triagle ETH have more space to the up side.
b) If wave iv of iii of iii made a simple zig zag this minor wave v could be an ending diagonal close to finished.
