Hi,
If you just need arrow up/down then comparing last value with new value is enough in my opinion, when last value is 19 and new is > then last value then tendency is "UP" and when new value is < last value then tendency is "DOWN", to make it more stable / less fluctuating you could make a average of last 5 values and compare it with new value.
