If we are daily trading then monitoring price movements is a must, we can get a lot of profit if we continue to monitor prices, and profit is something that we must get, of course it is not easy to keep observing price movements, using simple things, for example after buying and then we sell by adding profit on spot exchanges is a very good thing.
Monitoring prices is only a must for those who like to trade in the short term, because for those who like to invest in the long term, I don't think it is a necessity to continue to spend their time monitoring prices in the market. In addition, those who like to monitor prices are those who have bought before and set a high price with the profit level they want even though the price level they set is not certain to be reached in the near future. Unless there is a more significant price increase in the market.
And one more thing, those who only monitor prices without ever buying before, are those who will get nothing more than just being a very loyal market audience. So the necessity in terms of monitoring prices on the market also depends on what pattern someone is working on because not everyone does the same pattern so not everyone also has to monitor the market every day.
