Well I am not an expert trader but I've been here for almost 2 years and I think that most important indicator for a pump is social media . If a important man comes in the front of TV / social media and is starting talking about a virtual coin surely there will be a pump
Fundamentals are important but not all the times it can really give out some affect on the markets price.If theres a fud then expect either it would just stay or would decrease but one rule i do always follow is when theres a positive news its better to sell out immediately rather than on buying or accumulating even more.These are the things on where most traders do commit mistake.Doing fomo
when seeing bullish news without even realizing that they are already behind.
There is no indicator which is going to tell you when to buy or sell. They are lagging and you simply cannot rely only on indicators. Try using simple support & resistance lines connected with volume and price action. This should solve all your problems
Price actions is good but with volatility it will really give you some headache.
