dojo_forex_kline — FX Daily Bars

Overview

Daily OHLC and amplitude for major currency pairs. Used to convert revenue, profit, and other filing amounts into a single currency when report currency and listing/analysis currency differ.

Typical case: regional revenue in HKD in dojo_main_income while analysis targets USD — apply HKDUSD (or equivalent) at the report date.

Intended Use: Cross-Currency Revenue Breakdown

dojo_main_income region slices (mainop_type = 3) and dojo_fin_indicators currency store amounts in original report currency. This dataset is needed when:

Scenario Description
Listing market ≠ report currency e.g. HKD regional revenue vs USD analysis
Cross-region mix Normalize CNY / HKD / USD segments before computing mix %
Valuation alignment Market cap and price are in trading currency; revenue mix needs the same unit

Conversion Flow (reference)

  1. Read segment revenue and currency from dojo_main_income.
  2. Determine target currency from listing market in dojo_stock_info.
  3. Fetch FX rate for report_date from this dataset (e.g. HKDUSD, USDCNY).
  4. Convert main_business_income and recompute mbi_ratio.

Example 

Filing: Region "Hong Kong" = HKD 1.0B (currency: HKD)
Target: USD presentation

FX on report_date: HKD-USD close → HKD 1.0B × rate ≈ USD X.XB

Use close vs open and period-end vs filing date consistently in your own pipeline.
