Yeah, thats why I usually sell some in levels.. I write orders to sell all coins near the base right after I get some coins, incase there is a reaction spike.. but as time goes by, like a few hours after my entry, then cancel that first sell order, because a reaction spike is less likely and I start to layer sells all the way back up to the base. Like you I have often missed my sell.. But after you miss it, its not the same odds any longer, its a toss up now.. it might turn back up and it might not.. The odds are no longer in your favor, its 50/50 now for XRP..
As far as LGD goes, its very hard to know what to do with that trade, I would be scratching my head? That looks like a news drop to me, because why would all the buyers disapear like that... I dont usually throw good money at a bad trade.. But you are right, that it has respected bases in the past.. Gah, its hard to know what to do.. There must be some news out there somewhere because it looks so ugly now.. Atleast make sure to take a break even, or small loss on the next bounce.. my rule is to always participate (sell some) on every bounce, when Im in a trade gone bad.. You have a real stumper here.. if I get some time today I might try to look up this coin for news for you.
