+// IMPLEMENTATION PLAN
+
+// Script Pseudocode
+// Step 0a: Verify if the user provided an input parameter for the script.
+//   Supported parameter: `weeksBack`, which indicates how many weeks to look back.
+//   weeksBack=1 means last week only, weeksBack=10 means the last 10 weeks
+//   (excluding the current week). If no parameter was provided, set to 1.
+// Step 0b: initialize resultDict: Key=DateString, value=VolumeData for that week
+// Step 1 : Initialize connection to alphadex
+// Step 2a: Fetch all available pairs for DeXter (PlatformId=4)
+// Step 2b: Create and populate a pairAddress -> pairName dictionary
+// Step 3 : Get lastWeeks array
+// Step 4 : For each week, do this:
+// Step 5 :   For each pair, do this:
+// Step 6 :     a) set currentSelectedPair to the pair
+//              b) set canclePeriod to 1W
+//              c) get the pairName based on the pairAddress
+//              d) get Volume of that week from candle stick data
+//                 and set resultDict[weekStr][pairName]: volume
+
+// Helper functions needed
+// getLastWeeks(n: number): Date[]
+// -> returns array of dates, each date represents the start of a week (Monday).
+// -> the current week is not included
+// -> if run without parameters, it returns a sigle date, which is last weeks monday
+// -> we return last week, because the ongoing week is not finished yet
+
+// dateToUnixTimestamp(date: Date): number
+// -> Number(date) -> returns unix timestamp of a date
+
+// dateToDateStr(date: Date, returnFormat: "DD-MM-YYYY" | "YYYY-MM-DD): string
+// -> returns the date in the specified return format:
+//    - DD-MM-YYYY (needed for coingecko historic API)
+//    - YYYY-MM-DD (needed for google sheet KPI tracking)
+
+// Coingecko.getHistoricPrice(date: string, coinId: string): number
+// -> given date (day in the format "31-12-2023") and the coinSlug (e.g. "radix")
+//    returns the historic USD price on that day.
