Hindsight analysis is no fun for sure. But you also know that the first candle on the left side was at one time the last candle on the right side of the screen. Nothing's new under the sun around here.
Everyone's brain is wired differently, some people see things which others can't, as well we are biased and have different interests, we see things we are interested in and don't see things we are not interested in. I can't intraday trade because I don't want to, as well I believe it is more difficult than longer term swing trading, so these biases affect me by "I can only achieve what I believe I can achieve". Bar by bar, I have no clue, nor do I wish to know, but Schizo for example may have a very high success rate bar by bar but maybe fail to know how the big picture will unfold, just using as an example. The other thing the machine robot does is rotate from one sector to the next. It may pursue one sector and not another, for example recently uranium and coal were hot, now they are going cold, later they'll turn hot again, Lithium went cold, shortly hot, Nasdaq Index rotates as does Dow and Russell etc. There are times when a long swing trader shouldn't trade, I don't use MA's but some say don't trade below MA200, I use a different method, a countback of 65 days is a good idea, but I use a different method again. So sometimes the machine is programed only to take short trades, how it does that, gawd only knows, ie shorting stocks simply, I have no clue how they would obtain than method. I am aware for example, if AustralianSuper take a large position in a stock, runthefuckaway, as that stock will be shorted hard. So sectors go up and down like piano keys and if you're a stock trader you target the hottest stocks in each hottest sector. The best, simplest, roughest, fastest way to identify hot stocks is using a ratio volume divided by stock price. Be aware hotstocks run up and down hard, don't become a bagholder, don't fall in love.
No pattern as such, just straight lines. All trends are straight lines. At times the straight lines are broken by noise. As mentioned, I don't trade intraday as to do so it would be best imo to use algo programed automation, don't attempt manually as it will grind you down imo. There is always noise, but you need to deal with that in your own way in the timeframe you trade.
Crypto behaves technically, easy to trade, moves fast. Here it is behaving perfectly atm, no surprises.
