The only way is to set a sell order at these price points. Alerts will catch them but once you anticipate it may be too late. I like to use just a couple of charts which has good history of these spikes with enough frequency. EOS/XBT on Kraken is one of my faves. No big spikes in last couple of days, so hoping for some in next 24 hours
reading the chart effectively will always tell you what you can do to profit.. this is a great example of good chart reading.. it likes to spike, so why not layer some sells .. awesome job
