We are seeing #$SIREN is pumping now. So what I do is if I am planning to short then I just place a stop limit order below the current market price. So I have already placed the order at 0.5$ if the prices keeps moving up I adjust it accordingly.

Sometimes it works but sometimes the order gets executed but the price moves up again. For those cases I place a stop loss. And since I only use a small amount like 10-20$ even if it liquidates I don't take a huge loss.
