Notes

• mode is required and case-sensitive. Omission, LIVE, or paper returns HTTP 400 and places no order.

• live returns HTTP 409 until live trading has been explicitly enabled on this strategy in the browser.

• A partial entry success is HTTP 200. Inspect every legs[].ok result.

• ok: true with acknowledged: false is a broker-accepted order whose acknowledgement needs reconciliation; it is not a rejection or a reason to place a duplicate order.

• A second start while the strategy is running returns HTTP 409.

• This endpoint is for batch strategies and enforces it. A start against a signal strategy returns HTTP 400 with A signal strategy has no start. Its run opens on the first long_entry or short_entry signal after the session boundary., and nothing is claimed or resolved.

• A run whose entries were all rejected is closed immediately and returns HTTP 400. The message carries the venue's own reason, for example Every entry order was rejected: MIS orders cannot be placed after square-off time (15:15 IST). Trading resumes at 09:00 AM IST. When legs were refused for different reasons, each is listed against the leg it belongs to.
