help with indicator programing please

I would like help , im trying to write and indicator in a charting software package called prorealtime, and keep getting an error message when i validate the program.

the error is " a positive integer field is expected with []"
and the code i have writen is

c1= highest[2](high)<highest[9](high)
c2=(low[0-4]<lowest[3](low))
c3=(lowest[4](high)>(lowest[4](low)>lowest[23](low)))
c4=(close[0]>(0.5*(highest[2](high)-lowest[2](low))))
c5=(adx[4]>25)
c6=(highest[5](high)-(lowest[5](low)>1*averagetruerange[19]))
c7=open[0]=close[0]
C8=(lowest[2](low)>lowest[9](low))
c9=(high[0-4]>highest[3](high))
c10=(highest[4](low)<(highest[4](high)<highest[23](high)))
c11=(close[0]<(0.5*(lowest[2](low)+lowest[2](low))))
c12=(adx[4]>25)
c13=(highest[5](high)-(lowest[5](low)>1*averagetruerange[19]))
c14=open[0]=close[0]

// long set up
if c1 THEN
if c2 then
if c3 then
if c4 then
if c5 then
if c6 then
if c7 then
res = 1
endif
endif
endif
endif
endif
endif
endif
//short set up
IF c8 THEN
if c9 then
if c10 then
if c11 then
if c12 then
if c13 then
if c14 then
res = -1
endif
endif
endif
endif
endif
endif
ENDIF
Return res As "signal

any help much appreciated

Its very hard to get support on these boards with anything that's not MQL. But, just quickly looking at your code, I did see:

c14=open[0]=close[0]

Maybe this is a specialized language, but most programming languages don't allow double assignments like this. Are you sure this line is correct?

Many Thanks for having a quick look, i'll go and change it it shoud be <> not =. but that whats happens when you write it at 2am in the morning.
