TradingView to Rithmic: Account IDs and Contract Roots

TradingView documents webhooks as POST requests to an external URL. Rithmic documents developer interfaces into its trading infrastructure, including R | API+, R | Protocol API, and R | Diamond API. Those APIs are not generic unauthenticated webhook collectors. A receiver must translate the signal into the interface and deployment path for which the application has access, credentials, entitlements, and any required conformance.

Account and contract are separate namespaces. An email, prop-firm display name, TradingView broker label, or chart ticker is not necessarily the value the execution interface expects. The bridge should establish the Rithmic system and account during connection setup, then discover or validate a tradable contract. Never concatenate user-visible labels and hope they match a production identifier.

The reviewed Rithmic API page describes R | API+ for C++ and .NET applications, R | Protocol API as a WebSocket and Protocol Buffers path usable from different languages and operating systems, and R | Diamond API for specialized Linux and co-location use. These are not drop-in aliases. SDK shape, message lifecycle, operational requirements, and access process differ, so a connector should name its actual interface.

Rithmic says developers can begin against its test system and that production connectivity requires the applicable conformance process and live credentials coordinated with Rithmic and the broker or FCM. Do not advertise production Rithmic support based only on decoding a public protocol sample or reaching a test gateway. Conformance, credentials, market-data entitlements, and the account provider remain part of the real deployment.

A Rithmic login may be associated with a particular environment or system, and the resulting session can expose account context according to its entitlements. A bridge should not let the alert choose an arbitrary account string. During setup, it should authenticate, retrieve or confirm the accounts available to that session, and require an operator to select the exact destination. Persist the stable identifier and the surrounding environment information needed to detect a mismatch.

This is especially important when a trader has evaluation, funded, personal, or multiple-provider credentials. Similar display labels can conceal different systems and risk rules. Store a human-readable nickname only as presentation. At execution time, compare the configured broker-native account against the active session, reject unknown or duplicate matches, and log the chosen route before order submission.

TradingView strategies are often built on continuous symbols because they provide a convenient historical series. Brokers execute listed contracts with expiries. The bridge therefore needs a deterministic roll-aware mapping from the strategy root to a specific contract for the venue and account. It should obtain reference data through the approved Rithmic interface or a controlled catalog rather than infer a code from the calendar alone.

Contract roll is a policy decision, not a universal date. Volume can migrate before expiration, strategies may require a fixed roll rule, and account providers can impose restrictions on back months or positions near delivery. Store the selected contract beside the strategy deployment, expose its expiry to the operator, and reject an alert if the map is missing, stale, or points to a contract that is not entitled.

The payload should not contain Rithmic credentials or a free-form production account. A compact event can identify strategy, product root, side, desired quantity, event ID, and generation time. The route or authenticated webhook key selects a deployment. That deployment points to one approved Rithmic connection and one account allowlist, while the contract resolver turns the root into an exact instrument.

If a strategy truly needs to target a specific expiry, represent that as a validated contract key and still check it against discovered reference data. Quantity from the message remains a request, not authority. Apply product, account, and stage-specific caps before generating a Rithmic new-order message, and preserve the event ID through execution reports for reconciliation.

An HTTP receiver can acknowledge the webhook before a broker outcome exists. Rithmic order management is asynchronous, so the service should connect order updates and fills to the original event. Persist intended account, exact contract, side, quantity, client correlation, and every broker-native identifier returned. Partial fills must update remaining quantity; rejects must preserve the reason; cancel requests must not be reported as cancelled until confirmed.

Connection loss creates uncertainty. Do not assume a disconnected socket cancels server-side orders or proves that a submission failed. On reconnect, recover working orders, executions, and positions using the supported interface and reconcile them against durable intent. Block a conflicting retry while the original outcome is unknown. Emergency procedures should include a broker-native way to view and manage exposure if the bridge is unavailable.

First document the approved Rithmic API rail, environment, credentials owner, and any conformance status. Separately capture current broker, FCM, and prop-program rules. Then connect read-only, enumerate the intended account, retrieve reference data, and display the exact micro contract. Confirm tick size and value from the exchange specification rather than copying assumptions from a full-size contract.

Run failure drills before increasing size: duplicate alert, unknown root, stale expiry, invalid account, reject, partial fill, socket interruption, and process restart. The system should either reach a reconciled outcome or stop safely with an explicit unknown state. A connector is ready when the operator can answer which account, which dated contract, which order, which fills, and which resulting position from one trace.
