I’ve noticed lately that a good time to catch swings is when the Korean markets are trading heavily, generally on their open and close of their business hours. I think they are in the GMT+9 timezone if I’m not mistaken. For me on the east coast their heaviest trading seems to be around 5-6 am, so that would be like 2-3 am on the west coast unfortunately. This is particularly true when a coin is listed on a Korean exchange as happened with Monero a couple of days ago.
I think the traditional market hours in the US are also good to watch, as there can be high volume in the mornings in the US on news that happened overnight while folks were asleep. FOMO kicks in pretty heavily when people wake up to a huge market move that’s already underway.
Other than that, watch general crypto news sources for news that might indicate a shift in market sentiment leading to a breakout of a price on a specific crypto. Unfortunately, that can happen at lots of different times, and often the news comes too late in the move to take advantage of unless the report is fresh and not baked into the price already. If you are watching a specific coin, twitter feeds related to that crypto are a good place to get a heads up on what events they may have coming up so you can prepare in advance in case the news is big enough to swing the market.
For BTC, the trend is still very bullish, so I don’t see it coming back down for a few weeks. If you’re patient, you might be able to catch a retracement, but BTC almost always jumps back up above the retracement within a day or two unless there is some reason the price is being suppressed like the hard fork that recently took place. That’s coming up again toward November with the Segwit2X nonsense, so until late September I’d say the price will remain bullish generally.
Can’t say much about Ethereum personally as I haven’t watched it closely enough, but it did just have a big move to the upside that may be peaking from what I gleaned from tidbits of news here and there. Then again, it could stay bullish for a long time like BTC… hard to say on that one.
Essentially, crypto markets run 24 hours a day, so pick a time frame that works for you consistently, and track it during that time daily. There are tons of other people that have 9-5 jobs that only trade in their offtime, so I would expect market swings would sync up to periods when traders are most active, i.e. after work for people who don’t trade professionally, and during business hours for people who do it for a living.
I doubt that’s super helpful, but from my experience that’s what I’ve seen
One other note, if you study technical analysis of markets, you can predict when moves will be likely to occur and plan in advance setting up your trades ahead of time with stop limits and buy orders at particular price points. That will allow you to do it whenever you want, and it will trigger regardless of whether you’re at your computer able to press the button to make it happen. It’s definitely worth the time to get up to speed on how to view market trends. The video Peter did about the 7 most common trend patterns to look for in crypto is super helpful in that regard.
