Hi!

I am using talib in my project, my current setup:

  • osx: 12.2.1
  • talib 1.1.3 (according to talib.version) and 1.1.4 according to package_lock.json
  • npm 8.5.0
  • node v14.16.1

In short: I cannot use the BBANDS method - with the basic setup.

Code:

const tmpData = [
  42041.13, 42099.98, 41663.77, 41690.84, 41892.95,    41940,
  41765.24, 42154.26, 42290.41, 42027.43, 42067.01, 42205.42,
  42107.81, 42500.07, 42465.61,    42500,    42565, 42624.97,
  42553.66, 42227.85, 42102.29, 42171.93, 42215.33, 42659.99,
  42525.14, 42561.04, 43443.33, 43538.01,  43535.1,  43445.1,
   43543.2,  43523.7,  43665.7,  43970.4,  44027.5,    44235,
   44214.4,  44161.8,  44230.9,    44235,  44190.3,  44110.9,
   43928.2,  44114.2,  43989.6,  44129.8,    43975,  44164.8,
   44529.6,  44195.1,  43987.2,  44066.1,  43970.9,  43886.9,
   44044.9,  44026.3,  44165.5,  44134.5,  44002.8,  44092.8,
   44160.6,  44035.8,  43638.9,  43492.2,  43588.5,    43630,
   43560.2,  43817.8,  44202.2,  44078.7,  44050.4,    44000,
   43860.7,  44050.2,  44001.9,  43994.2,  43574.3,    43600,
   43613.8,  43819.9,  43902.4,  43461.4,  43214.7,    43050,
   43158.2,  43207.5,  42242.6,  41919.9,  41907.7,  41968.8,
     41730,    41265,  41177.1,  40865.6,  40643.4,  40691.7,
   40491.7,    40545,  40766.5,  40745.5,] 
 
 let result = await talib.execute({
                name: "BBANDS",
                inReal: tmpData,
            });

What I got:

Fatal error in , line 0
Check failed: receiver.IsJSFunction().
FailureMessage Object: 0x3087d5510
 1: 0x1001142e2 node::NodePlatform::GetStackTracePrinter()::$_3::__invoke() [/usr/local/bin/node]
 2: 0x1010106d2 V8_Fatal(char const*, ...) [/usr/local/bin/node]
 3: 0x1005782d8 v8::internal::JSReceiver::GetCreationContext() [/usr/local/bin/node]`

No matter the length of the data, I am still receiving the same results.
Not sure where I should be digging/checking as the information I found about a similar issue is pointing only to an empty array being passed to the Talib method - that is not the case in my example.

Edit:
I will be updating my findings here:

  • Same problems on 1.1.2 & 1.1.3 & 1.1.4 (interestingly this version still introduces itself as 1.1.3)
  • Other methods works - "CDLTHRUSTING", "CDLXSIDEGAP3METHODS", "CDL3BLACKCROWS", "CDL3STARSINSOUTH", "CDL3WHITESOLDIERS", "CDL3INSIDE"
  • The only difference I see is the type of data - in the methods I was using before I got type: 'price', in BBANDS I got type 'real' - investigating.

FIXED!

Looks like

optInTimePeriod: number,

Is a mandatory parameter!
