Exit Strategy is really important for you to avoid huge loss.

What I do is I really respect my entry and exit points according to the studies showing in the graphs. I suggest you also try to learn on reading the studies where in you would determine if an alt is bound to go up or down. And then if you reached an entry point position, learn how to accept and respect your cut loss point. Like for example if you had already reached your risk appetite of loosing around 2-4% then exit right away and don't look back. Just focus on your other trades and look for other opportunities. Same goes if you reached already a certain percentage of gain. Profit is profit and you wont have to maximize every upward trends as we will never be sure when will it crash. I do this in both trading alts and stocks.
