context_get_orderbook. Use context_get_oracle for the oracle's evidence summary, and if you need a numeric oracle quote use ctx.markets.latestOracleQuote(marketId) from the SDK. The midpoint of the current bid-ask is a starting reference; the latest oracle quote is a separate pricing input.ctx.orders.bulkCreate() with both a buy and sell order, or two separate ctx.orders.create() calls.context orders create --outcome yes --side buy --price <bid> --size 10 and context orders create --outcome yes --side sell --price <ask> --size 10context_place_order({ marketId, outcome, side, size, price })ctx.orders.mine(marketId) or context_my_orders. When one side fills, the other is still open.ctx.orders.bulk() for atomic cancel+create to avoid being temporarily unquoted:
await ctx.orders.bulk(
[newBuyOrder, newSellOrder], // creates
[oldSellNonce], // cancels (execute first)
);
bulk() for atomic rebalancing. Cancelling and placing separately creates a window where you have no quotes — other participants can move the price against you.context_get_oracle for evidence and summary text, not latestOracleQuote().context_get_balance regularly. Ensure your settlement balance can cover the new orders. Insufficient balance will cause orders to be voided.context_get_orderbook.ctx.orders.mine(marketId) or context_my_orders should show two open orders — one buy, one sell — at your desired prices.
