The Scenario
You run a mean-reversion strategy on 20 forex pairs. Your strategy sheet in Google Sheets needs current bid, ask, previous close, and the past 30 days of daily OHLCV bars for each pair — two different data shapes, pulled from two different Finage endpoints. You've been pulling quotes from one tab and bars from another, manually, once a week before your strategy review.
The third week in a row doing this, you realize the process itself has become the job.
The bad version:
- Call the Finage forex quote endpoint for each pair, copy the bid and ask, paste into the quotes tab — 20 pairs, 20 pastes.
- Switch to the historical endpoint, retrieve 30 days of bars for pair 1, export, paste below the header row. Repeat 19 more times.
- Discover that two pairs returned bars in a different number of rows because of a bank holiday in the quote currency country, and your downstream formulas are now misaligned.
Your strategy cannot run until the data is clean and aligned. The time you spend on the data pull is time you are not spending on the strategy.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your Google Sheet that connects to Finage directly. It reads your pairs, calls the quote and historical endpoints, and writes both data shapes into the appropriate locations in your sheet — no export, no alignment fix, no endpoint juggling.
For each forex pair in column A of my Google Sheet, fetch the latest quote and previous close from Finage and write bid, ask, and prev close into columns B through D
What You Get
- Column B: current bid price
- Column C: current ask price
- Column D: previous session close
- Pairs that return no data surface a note in column E so nothing silently blanks
What If the Data Is Not Quite Ready
You also need 30 days of daily bars for each pair, written below each pair header
For each forex pair in column A, fetch the current quote from Finage and write bid, ask, and previous close into columns B through D, then fetch 30 days of daily OHLCV bars and write them below the pair header starting in the row below
Some pairs in your list include exotic currencies that Finage covers differently
For each pair in column A, check whether Finage returns a standard quote or requires the exotic forex endpoint, then fetch the current bid, ask, and previous close using whichever endpoint applies and write the results into columns B through D
You want to add the 30-day average spread alongside the current quote
For each forex pair in column A, fetch the current quote and 30 days of daily bars from Finage, write bid, ask, and previous close into columns B through D, and in column E write the average daily spread (high minus low) across the 30-day lookback period
You want to clear the previous week's data, reload everything, and flag pairs where the current spread exceeds the 30-day average by more than 50%
Clear all data below the headers on my Forex Strategy sheet, fetch current bid, ask, and previous close from Finage for each pair in column A, fetch 30 days of OHLCV bars, calculate the average daily spread, and in column F flag any pair where today's spread is more than 50% wider than the 30-day average
One prompt covers the data refresh, the derived calculation, and the alert logic end to end.
