Can anyone help converting the code below ? Thanks

if it’s too long, can you please convert only the following part? Thanks a lot!

_rate(cond) =>
ret = 0.5 * (tw + bw + (cond ? 2 * body : 0)) / (tw + bw + body)
ret := nz(ret) == 0 ? 0.5 : ret
ret

plot(ctl, title = “CDV Line”, color = color.blue, linewidth = 2)

Please post screenshots of how it looks, it fastened the comprehension of the code and its translation.

Pretty close, without the HH candles:

var
ctl,
o, h , l, c, tw,
body, rateup, ratedown, ku, kd, bw, k2,
deltaup, deltadown, cumdelta, deltaa: float;

begin
tw := high – f_max(open, close) ;
bw := f_min(open, close) – low ;
body := abs(close – open) ;

if open <= close then ku := 2*body
else ku:=0;
rateup := 0.5 * (tw + bw + ku) / (tw + bw + body) ;
if rateup = 0 then rateup := 0.5
else rateup:=rateup;

if open > close then kd := 2*body
else kd:=0;
ratedown := 0.5 * (tw + bw + kd) / (tw + bw + body) ;
if ratedown = 0 then ratedown:= 0.5 else ratedown:=ratedown;

deltaup := quantity * rateup ;
deltadown := quantity * ratedown ;
if close >= open then deltaa := deltaup
else deltaa := -deltadown;
cumdelta := cum(deltaa);
ctl := F_Smoother( cumdelta);

plot(ctl);
end

Here is a code translated from different versions you shared in the thread for the Cumulative Volume Delta:

tw = high - max(open, close)
bw = min(open, close) - low
body = abs(close - open)

if open<=close then 
deltaup = 0.5 * (tw + bw + (2 * body)) / (tw + bw + body)
endif

if open > close then 
deltadown = 0.5 * (tw + bw + (2 * body)) / (tw + bw + body)
endif 

if close >= open then 
delta= deltaup 
else
delta= -deltadown
endif

cumdelta = cumsum(delta)

drawcandle(cumdelta[1],max(cumdelta, cumdelta[1]),min(cumdelta, cumdelta[1]),cumdelta)
return

tw = high - max(open, close)

bw = min(open, close) - low

body = abs(close - open)

if open<=close then

deltaup = 0.5 * (tw + bw + (2 * body)) / (tw + bw + body)

endif

if open > close then

deltadown = 0.5 * (tw + bw + (2 * body)) / (tw + bw + body)

endif

if close >= open then

delta= deltaup

else

delta= -deltadown

endif

cumdelta = cumsum(delta)

drawcandle(cumdelta[1],max(cumdelta, cumdelta[1]),min(cumdelta, cumdelta[1]),cumdelta)

return

Sorry there was no volumes in the previous version, correct one is below:

tw = high - max(open, close)
bw = min(open, close) - low
body = abs(close - open)

if volume then 
if open<=close then
deltaup = volume*(0.5 * (tw + bw + (2 * body)) / (tw + bw + body))
endif

if open > close then
deltadown = volume*(0.5 * (tw + bw + (2 * body)) / (tw + bw + body))
endif
endif

if close >= open then
delta= deltaup
else
delta= -deltadown
endif

cumdelta = cumsum(delta)

drawcandle(cumdelta[1],max(cumdelta, cumdelta[1]),min(cumdelta, cumdelta[1]),cumdelta)
return

tw = high - max(open, close)

bw = min(open, close) - low

body = abs(close - open)

if volume then

if open<=close then

deltaup = volume*(0.5 * (tw + bw + (2 * body)) / (tw + bw + body))

endif

if open > close then

deltadown = volume*(0.5 * (tw + bw + (2 * body)) / (tw + bw + body))

endif

if close >= open then

delta= deltaup

else

delta= -deltadown

endif

cumdelta = cumsum(delta)

drawcandle(cumdelta[1],max(cumdelta, cumdelta[1]),min(cumdelta, cumdelta[1]),cumdelta)

return
