Should the 90 day high be breached, I expect the next major resistance would be around the 9 month high (ETH 0.190).
Taking profits close to the 9 month high resistance (ETH 0.175 - 0.200) region may be a good idea.
Exit with a 30 or 14 day trailing stop loss. Perhaps also bail if there are signs of a reversal near ETH 0.09.
If you haven't already now is a good time to set up your stops on the 30 day low (ETH 0.044)
