Translation from probuilder to ninjascript

[PScilly]

Hi everyone, I tried to translate one of my trend indicators based on std deviations from probuilder to ninjascript but the trend change logic doesn't always work on ninja as it does on prorealtime.
I attach here the original probuilder code, can someone help me pls? Thanks a lot

// Costants.
// The six trend values are fictional

period = 13
deviation1 = 1
deviation2 = 2
longupper= 30
longmiddle=20
longlower=10
shortlower=-30
shortmiddle=-20
shortupper=-10

// (i) indicators
iSTD1 = deviation1 * STD[period](close)
iSTD2 = deviation2 * STD[period](close)
iSTD3 = deviation3 * STD[period](close)
iSMA = Average[period,0](close)

// (c) conditions

cUpperBand2 = iSMA + iSTD2 // ----2----
cUpperBand1 = iSMA + iSTD1 // ----1----
cMiddleBand = iSMA // ----0----
cLowerBand1 = iSMA - iSTD1 // ----1----
cLowerBand2 = iSMA - iSTD2 // ----2----

// Bollinger's Logic

// Initial set trend, based on first std dev

if trend=0 and close crosses over cUpperband1 then
trend = longupper
elsif trend=0 and close crosses under cLowerBand1 then
trend = shortlower
endif

// Follows first set trend
// Change of trend

if trend = longupper and close crosses under cUpperBand1 then
trend = longmiddle
endif



if trend=longmiddle then
if close crosses under cMiddleBand then
trend=longlower
elsif close crosses over cUpperBand2 then
trend=longupper
else
trend = longmiddle
endif
endif

if trend=longlower then
if close crosses under cLowerBand1 then
trend=shortlower
elsif close crosses over cUpperBand1 and close < cUpperBand2 then
trend = longmiddle
elsif close crosses over cUpperBand2 then
trend=longupper
else
trend=longlower
endif
endif

if trend=shortlower and Close crosses over cLowerBand1 then
trend=shortmiddle
endif

if trend=shortmiddle then
if close crosses over cMiddleBand then
trend=shortupper
elsif close crosses under cLowerBand2 then
trend = shortlower
else
trend=shortmiddle
endif
endif

if trend = shortupper then
if close crosses over cUpperBand1 then
trend=longupper
elsif close crosses under cLowerBand1 and close > cLowerBand2 then
trend=shortmiddle
elsif close crosses under cLowerBand2 then
trend=shortlower
else
trend = shortupper
endif
endif

// defines the values of 'ts' at the appropriate Bollinger band level

if trend = longupper or trend = shortupper then
ts = cUpperBand1
elsif trend = longmiddle or trend = shortmiddle then
ts = cMiddleBand
elsif trend = longlower or trend = shortlower then
ts = cLowerBand1
endif

// colors

if trend = longupper or trend = longmiddle or trend = longlower then
r = 0
g = 255 // colors the "ts" trendline in green


elsif trend = shortupper or trend=shortmiddle or trend=shortlower then
r = 255 // colors the "ts" trendline in red
g = 0

endif

return ts coloured(r,g,0) style(line,2) as "BTrend"
