this is ehler fisher transform code pl do find a way to tradescript i hope there is always a way
Length = input(10, minval=1)
xHL2 = hl2
xMaxH = highest(xHL2, Length)
xMinL = lowest(xHL2,Length)
nValue1 = 0.33 * 2 * ((xHL2 - xMinL) / (xMaxH - xMinL) - 0.5) + 0.67 * nz(nValue1[1])
nValue2 = iff(nValue1 > .99, .999,
iff(nValue1 < -.99, -.999, nValue1))
nFish = 0.5 * log((1 + nValue2) / (1 - nValue2)) + 0.5 * nz(nFish[1])
pos = iff(nFish > nz(nFish[1]), 1,
iff(nFish < nz(nFish[1]), -1, nz(pos[1], 0)))
barcolor(pos == -1 ? red: pos == 1 ? green : blue )
plot(nFish, color=green, title=“Fisher”)
plot(nz(nFish[1]), color=red, title=“Trigger”)
