I like to use correlation for clues for overall market sentiment, and to help gauge these particular Alt's. I use BTC as a marker of sorts and I've noticed for the most part these Alt's have been following BTC well, and at much faster percentage rate up and down!!.. For example I've noticed ADA moves upward much faster percentage wise then BTC, but then runs out of momentum quicker, whereas ETH will keep its momentum a bit longer before it pulls back or reverses trend. I've noticed when this happens ADA, NEO, XRP, XLM, will sometimes retest their recent highs as they have pulled back, while BTC and ETH are still getting to their high... When this occurs it sometimes helps me find a nice trade with these particular Alts... I just make sure that I exit them timely as they can come down rather quickly once BTC reaches its high... so I like to mark out all the ceilings (Breach areas, EMA's to bounce of off, Regression trends to stay in or break, etc.) on the different time frames ( 4hour, 1day, 1week mostly for me) and pay close attention to and try to gauge the momentum of BTC to see if its going to break the ceilings/floors and which ones on the different time frames, and I like to watch for over bought/sold conditions and divergence ( for that I like to use the MacD, Stoch, RSI, DMI) on the different time frames to further help me gauge the momentum for my exits/entries... sometimes it's easy to read and sometimes not..!
