}Build a signable take-profit / stop-loss update intent
Sets or removes a position’s TP and SL prices (stopLoss=0 removes the SL; takeProfit=0 resets the TP to the pair’s max-gain cap — a position always has a TP on-chain). Returns an EIP-712 payload to sign (trader or a registered delegate may sign) and hand to the Avantis operator for gasless execution. Note: TP/SL updates are intent-only in v2 — there is no direct-transaction equivalent. Submit as via PUT /price-triggers/global---- on the core API, which executes it through the Avantis operator.

}Body
The trader (position owner). USDC collateral is pulled from and paid out to this address.
Position slot index for this trader + pair (0-based; a trader can hold several positions on the same pair). Read it from GET /v2/positions → trades[].trade.index.
x >= 0Take-profit price in USD. 0 or omitted = no take-profit (0 also removes an existing one on updates).
Stop-loss price in USD. 0 or omitted = no stop-loss (0 also removes an existing one on updates).
Pair index (alternative to pair).
x >= 0Pair symbol, e.g. ETH/USD (separators /, -, _ accepted; case-insensitive).
1Replay-protection nonce (uint256; unordered Permit2-style bitmap, not sequential). A random one is generated when omitted — only pass a value to pre-reserve or deterministically retry an intent. Check availability via GET /v2/nonce.
Intent expiry as a unix timestamp in MILLISECONDS (not seconds). Defaults to now + the service value shown in /v2/meta → defaults.intentDeadlineMs.
Response
Success envelope: ok is true and data carries the payload documented below.
Always true on success.
true A ready-to-sign EIP-712 payload. Sign {domain, types, primaryType, message} with signTypedData (trader or a registered delegate, per signerRule) and hand the 65-byte r||s||v signature to the Avantis service that executes this intent kind.
