loss = abs(min(source - source[1], 0))
If today's price < yesterday's: loss = |difference|
If today's price >= yesterday's: loss = 0
```Examples
// stock declined today
loss(close) > 0;// lost more than $2 today
loss(close) > 2;// total losses over last 14 days
sum(loss(close), 14) > 10;// today was a down day (loss exceeded gain)
loss(close) > gain(close);Returns
Float >= 0 (the absolute price decline, or 0 if price didn't fall) ## Notes - Always returns a non-negative value (losses are expressed as positive numbers) - Returns 0 on the first bar (no previous bar to compare) - Use with sum() or wilderma() to aggregate losses over time ## See Also gain, rsi, change
