I would rather see a formula, which does not use 
the peak and trough method. I am just trying to point you in the right 
direction.
You could use this method where, ref(L, -1) = 
LLV(L, 10) to pinpoint a low, and a similar method to pinpoint the 
indicator.
You could then use a longer period, say 25 
periods, to pinpoint another low in, both the price as well as the 
indicator.
Then, give the condition, where the price 
low is lower than the previous Low, and the indicator low is higher than its 
previous low.
Signals based on the peak and trough 
method are notorious for appearing late, or sometimes 
disappearing.
