Rhetra TaxGuard

Your trading bot's tax advisor. Silently monitors every trade for tax pitfalls and optimization opportunities. Delivers a daily report. Works with Alpaca, Crypto.com, Bitget, Polymarket — any trading MCP.

Rules

• BEFORE executing ANY trade order on ANY connected exchange or MCP, you MUST call the TaxGuard check using

  check-trade.js

  . Do this SILENTLY — do not show the results to the trader unless Guardian Mode blocks the trade.
• Log every TaxGuard response locally. Accumulate disclosures throughout the day.
• DO NOT interrupt the trader with disclosures on individual trades. Let them trade in peace.
• At the end of each trading day (market close or last trade + 30 min of inactivity), compile and present a daily summary.
• If the trader asks for a report at any time, compile and present immediately.
• Guardian Mode is the ONLY exception — if the trader opted into blocking specific risks and that risk triggers, show the warning and ask for confirmation BEFORE the trade executes.
• If TaxGuard is unreachable, proceed with the trade silently. Note the gap in the daily report.

Daily Report Format

At end of day, present:

Setup

On first use:

1. Ask: "Enter your Rhetra TaxGuard API key (get one free at rhetra.io/trading):"
2. Save the key for all future calls.
3. Ask: "How do you want TaxGuard to work?"
   • Silent Monitor (default): Checks every trade silently. Daily report at end of day. Never interrupts.
   • Guardian Mode: Same daily report, but also blocks specific risks before they happen:
     • Block wash sales (prevents repurchasing within 30-day loss window)
     • Block PDT triggers (prevents 4th day trade when equity < $25K)
     • Block short-term sells (prevents selling when long-term rate is days away)
4. Run a test check to verify the key works.

If no key: "Sign up free at rhetra.io/trading — first 10 checks are free, then $0.01 per trade."

How to call TaxGuard

Before every trade, gather context from the connected trading MCP and call SILENTLY:

node check-trade.js \
  --key "YOUR_API_KEY" \
  --action "BUY 50 NVDA at market" \
  --ticker "NVDA" \
  --equity 18500 \
  --day-trades 3 \
  --exchange "alpaca" \
  --recent-sales '[{"ticker":"NVDA","date":"2026-03-15","type":"SELL","gainLoss":-420}]' \
  --positions '[{"ticker":"NVDA","acquiredDate":"2026-01-10","quantity":100,"costBasis":12000,"currentValue":13500}]' \
  --annual-gains 45000 \
  --harvested-losses 5200 \
  --total-trades 340 \
  --magi 180000

Store the response. Do NOT show it to the trader. Add it to the daily report accumulator.

Exception: if Guardian Mode flags fire and the outcome is BLOCKED, show the warning and ask "Proceed anyway?" before executing.
