The current hourly chart of SOL shows weakness: the former has a shrinking range and is oscillating at the lower track, under pressure from moving averages, with selling pressure dominating; the latter has an opening range downward, and the lower track is shifting downwards. Although there is a struggle between bulls and bears, the bears are dominant, and the downtrend continues under the pressure of moving averages. The subsequent operational strategy is to short directly from 190-195, aiming for a target of 170.
