What Happens if There Are No Buyers or Sellers?

If your order is not filled, there may be no matching counterparty at your price. A buy needs a seller at your bid, and a sell needs a buyer at your ask. Until a match appears, the order stays pending.

Explanation

  • Order stays open in the book: Your order rests at the exchange at the price and quantity you set.
  • No execution without a match: Trades occur only when opposing orders cross on price and quantity.
  • Partials can happen: If there is some but not enough opposite side quantity, you may get a partial fill, with the remainder left open.
  • Validity controls behaviour:
    • DAY: Stays active until market close, then lapses if unfilled.
    • IOC: Fills whatever is available instantly and cancels the remainder.
    • GTT: Triggers when your condition is met. Once triggered, the resulting order follows its own validity.

How to improve fill probability?

  1. Check depth and spread: Review best bid, best ask, and available quantities.
  2. Nudge your limit price: Move closer to the opposite side in small increments to attract a match.
  3. Reduce or slice quantity: Smaller clips are easier to fill in thin markets.
  4. Use a marketable limit: Set a limit slightly above the current best price to balance speed and control.
  5. Avoid illiquid windows: Mid-session often has steadier liquidity than right at open or close.
  6. Reassess liquidity: Very wide spreads and low volume may warrant waiting or a different execution plan.
Use limit or marketable limit orders and check the order book depth to balance fill probability with price control.
