Example

Python

from fubon_neo.sdk import FubonSDK, Order

sdk = FubonSDK()

accounts = sdk.login("Your ID", "Your password", "Your cert path", "Your cert password")  # Login required to obtain market data permissions

sdk.init_realtime() # Establish market data connection

reststock = sdk.marketdata.rest_client.stock

## Version 2.2.6 and later use simplified approach (using Exception for error handling)
from fubon_neo.sdk import FugleAPIError

try:  
  reststock.technical.bb(**{"symbol": "2330", "from": "2024-08-01", "to": "2024-08-10","timeframe":"D", "period": 10})
except FugleAPIError as e:
  print(f"Error: {e}")
  print("------------")
  print(f"Status Code: {e.status_code}")  # Example: 429
  print(f"Response Text: {e.response_text}")  # Example: {"statusCode":429,"message":"Rate limit exceeded"}     

Node.js

const { FubonSDK } = require('fubon-neo');

const sdk = new FubonSDK();

const accounts = sdk.login("Your ID", "Your Password", "Your Cert Path", "Your Cert Password");

sdk.initRealtime(); // Establish market data connection

const client = sdk.marketdata.restClient
client.stock.technical.bb({ symbol: '2330', from: '2024-08-01', to: '2024-08-10', timeframe: 'D', period: 10 })
  .then(data => console.log(data));

C#

using FubonNeo.Sdk;
using FugleMarketData.QueryModels.Stock.History;   // Import HistoryTimeFrame
using FugleMarketData.QueryModels;                 // Import FieldsType



var sdk = new FubonSDK();
var result = sdk.Login("Your ID", "Your Password", "Your Cert Path", "Your Cert Password");

sdk.InitRealtime(); // Establish market data connection

var rest = sdk.MarketData.RestClient.Stock;

DateTime fromDate = new DateTime(2024, 8, 1);
DateTime toDate = new DateTime(2024, 8, 10);

var bband = await rest.Technical.Bb("2330" ,new(10, fromDate, toDate, HistoryTimeFrame.Day)); 
//BbRequest parameters (period, DateTime, DateTime, HistoryTimeFrame)

var bband_con = bband.Content.ReadAsStringAsync().Result;

Console.WriteLine(bband_con);
