Its not possible in an absolute way but you can determine when there is a strong trend and when volume is lacking for example.   If we repeatedly attempt but fail to pass a point it can be surmised as a reason to consider we might be encountering a point where the market might turn.   The 2018 low came year end into a time of holidays and possibly reduced volume in that time, price can go anywhere but the quality of trading action varies.   Right now price is near to the year low, it cant be said to be everything but its worth noting how we react to the recent low prices.
