SOL current price 95u, short position, stop loss 98u, target 89u.

98u is a recent strong resistance zone; SOL is unlikely to break through it in one attempt.
Once it rises to this level, it indicates that the bears have completely failed and the bulls are mounting a strong counterattack, rendering your short position meaningless. This stop loss distance is reasonable and won't be triggered by minor fluctuations.
89u is a recent strong support level, very likely to hold and cause a rebound rather than a further drop.
Sell half first = lock in part of the profit, no need to rush.
