can any one help me with this small.
var last_h = 1, last_h := last_h + 1
var last_l = 1, last_l := last_l + 1
var lw = 1, var hg = 1
lw := lw + 1, hg := hg + 1
p_lw = -lowestbars(Depth), p_hg = -highestbars(Depth)
lowing = lw == p_lw or low - low[p_lw] > Deviation*syminfo.mintick
highing = hg == p_hg or high[p_hg] - high > Deviation*syminfo.mintick
lh = barssince(not highing[1]), ll = barssince(not lowing[1])
down = barssince(not (lh > ll)) >= Backstep, lower = low[lw] > low[p_lw], higher = high[hg] < high[p_hg]
if lw != p_lw and (not down[1] or lower)
lw := p_lw < hg ? p_lw : 0
if hg != p_hg and (down[1] or higher)
hg := p_hg < lw ? p_hg : 0
i did my best but i couldnt understand pinescript at all.
