Dimitris,
The code I have given is correct.
As to yours "the distance from L==LLV(L,20) may be greater", please think again.
The distance from L == LLV( L, 20 ) can not be greater than 19.
LLV( L, 20 ) is just one of the value (the lowest) during
last 20 bars. Therefore L == LLV( L, 20 ) must be met in one of those
last 20 bars (counting from 0..19)
Best regards,
Tomasz Janeczko
