There are still options where the decline continues within the the correction model framework (or another). However, this doesn't mean that it's not worth buying. The risk in the market is always present. The question is the correctness of personal money-management. You can try to buy with short stop-loss at the top of the 1-blue wave. In case the stop loss works you may try to play short from the next zone according to the logic of movement, but performing additional conditions for sale (descent into the orange zone).
