The Psychology of Reversal probably only occurs short term if we keep checking the prices too often. I mean right after we buy or sell the chances are probably 50/50 for the price to move in our favour or against us. While it is important to check prices regularly, we shouldn't worry too much about short term gains or losses in my opinion. It is better to trade for the long run. Crypto currencies tend to move in cycles, so if we make some loss this year, we will likely recover next year. Instead of selling while my coins are red, I tend to just hold them longer and sell eventually with at least some profit.
Imagine the difference in checking every 5 minutes as opposed to even 50 minutes.
The brain needs rest and psychology is about behavior and repetition,,, so I agree. The more often you check, the more you build a pattern and repeat, the more your brain craves for that repetition.
That is why reversal psychology kicks in.
In this case, it happened to me particularly, when I was starting in the world of trading, I used to be watching every movement of the market day and night, waiting for the market to make the movement that I had set, and the truth was I was getting sick, so much of the body for sitting all day and of the mind because even sleeping I dreamed of trading.
The best thing for these cases is to get a good Exchange where in just 1 operation you can place:
1.- Stop Loss.
2.-Take profit.
In the case of Bitfinex it has it, and the option of leverage is available, of course not 100x like Binance, but if you have those options, then it is much easier to put the position with the stop and take profit, and go and wait for the movement If it was lost, it is time to assume the loss and if it was won, celebrate and on both occasions it is necessary to learn why it was lost or won.
