I wish I had a good answer for you. But this market is its infancy stages still and so there is often big differences in prices between the exchanges. Especially in a panic dive, some exchanges dive much further faster than others. So we cannot expect all charts for the same coin to fill there gaps. Play out the panic with me: all exchanges are trying to move in sync, so there never is an exchange that is still dropping while another exchange is running up. Timewise they are atleast moving in the same direction at the same time, or very very close. So when one exchange hits area of support, because it dropped futher on its chart then the rest, I will bounce, and the other exchanges will follow, because timewise they all try to follow each other.. You cannot expect the exchange that made it $500 lower than everyone, to stay at the bottom and keep handing out that deal until all the other exchanges catch up. And as soon as it starts to bounce hard, you cannot expect the other exchanges not to start a bounce even though they didnt panic as deep.. Its a baby market right now and there is a lot of arbitrage opportunity still. So its really hard to know if these gaps on some charts will ever fill, because these coins are not moving in sync yet (timewise and distance, only timewise)..
