Sheets: paste into cells

=ZV_WHOAMI()
=ZV_SPOT("USD","SEK")
=ZV_FORWARD("USD","SEK",13,TODAY()-1)
=ZV_VOL("USD","SEK")
=ZV_CARRY(B3,B4,13)
=ZV_SPOT_HISTORY("USD","SEK",TODAY()-30,TODAY())
=ZV_SPOT("USD","MXN")
=ZV_TCA_PNL(1000000,"SELL_USD",9.52,9.55)

TCA narrative

For USD notional and rates as foreign per 1 USD (e.g. USDSEK):

SELL_USD: (N × (arrival − exec)) / arrival → USD PnL
BUY_USD: (N × (exec − arrival)) / arrival

When ZV_TICK is live on staging, put the trade time in a cell and use it as arrival. Until then, paste an arrival mid manually into ZV_TCA_PNL.

Claude / MCP prompts

On claude.ai: + → Connectors → Add custom connector (no API key). See Claude. Keep the first prompt tiny; use a new chat for bigger work. Host tool budgets vs ZeroVaR access: usage limits.

Using only ZeroVaR staging MCP tools (do not web search), call whoami, then market_spot for USD/SEK MID. Report kind, level_name, rate, and as_of.
