script coding issue on TD


New member
Having an issues with TD accepting a script. If someone can take a look and let me know what I’m doing wrong when entering it in that would be great! Thanks!

below is the following script, and TD marks it as red cause my equal sign is invalid…

len = input(14, title = 'Length')

src = input(close, 'Source', type = input.source)

ob = input(70, 'Overbought')

os = input(30, 'Oversold')

timeframe = input('D', title = 'Timeframe', options = ['1', '3', '5', '10', '15', '30', '60', '120', '240', 'D', 'W', 'M'])

rsi = rsi(src, len)

rsi_htf = security(syminfo.tickerid, timeframe, rsi(src,len))

rsi_casabene = (rsi + rsi_htf) / 2

h1 = hline(ob, 'OB', color.gray)

h2 = hline(os, 'OS', color.gray)

plot(rsi, 'RSI',

plot(rsi_monster, 'RSI Monster',

fill(h1, h2, color.purple)

If this is thinkscript then I think you have to use 'def' to define your variables and close the line with a semicolon.
Def len = input(14, title = 'Length');

Yes it is thinkscript and I left def out so that might be the reason it’s not taking the code! I’ll try this and see!
This is not thinkscript and you clearly didn't write it. The tos version is already available from where you got this script from.
Correct, I did not write it I found it on a forum and wanted to use it in my indicator list. Didn’t realize it was already on there. What is the indicator called under TOS?
