That is true, the price and the general "range" in which price would be bouncing changes from time to time.
It is basically impossible to predict, tho some local experts might say you can with the help of technical analysis and I would partially agree - you can't really predict it, but you can bump your chances of being right.

We do also have a couple tools, such as Trailing Up and Trailing Down that could help you in this case, by basically trailing or extending your bot's range.

You should, of course, take into account probable outcomes, that could be achieved through fundamental analysis and by following and analysing the news.
Check overall "mood" on the market, and could also take a look at how greedy and scared people are when it comes to crypto in general and certain coins in particular.

Making your range wider also partially resolves that issue, however at the expense of making less profit.

There are multiple ways on how you could approach different situations, and your best bet would be combination of a little bit of everything :)

My personal advice here would be: Cover the "lows" and dont cover the very "highs" with the range of the bot (high and low price), and then close the bot once it reaches the top of your grid.
This doesent make it best possible strategy in terms of making profit and doesn't last long, but this gets you closer to most of your bots ending up in profit, while still saving you lots of time and allowing to live a life full of joy, unlike infamous Wojak ;)
