Orders and Execution
Targeted answers for orders that fail, fill unexpectedly, or behave strangely.
My order failed. The reason is on the order itself. Run through:
- Balance — confirm the account has enough of the right asset to settle: buying power at your broker, USDC margin in Perps, your Tokens balance (plus network gas), or pUSD for Polymarket.
- Venue status — broker market hours (stocks), venue status (perps), order-book depth (predictions). Off-hours or thin books cause rejection.
- The error message — the order panel shows the venue's exact error, for example "insufficient margin" or "market closed". For stock orders, you can also open the order from Orders on your account page.
Most failures are recoverable: address the cause and submit again. Alphio does not silently route to a different venue or asset.
Order shows executed but no position. Almost always a view mismatch, not a missing position:
- Account selector — you may be viewing a different broker account or wallet.
- Venue — perps live under Crypto Trade ▸ Perps, tokens under Crypto Trade ▸ Tokens, predictions in your Polymarket positions, stocks at your broker.
- Filters — clear them; an old default filter can hide today's fill.
If the order shows as filled but no position appears anywhere after a hard refresh, contact support with the order ID.
Does Alphio retry failed orders? No. If a venue rejects an order, the error is surfaced on the order and no further attempt is made. Alphio never re-routes to a different venue or asset to "force" a fill. Address the cause and submit again.
Can I set a slippage tolerance? For Tokens trades, yes — pick a Max slippage in the trade panel's settings; if the price moves past it before the trade lands, the trade is cancelled and no fee is charged. For stocks, perps and predictions there is no slippage setting: to control the price you pay, use a limit order instead of a market order — a limit order only fills at your price or better, at the cost of possibly not filling at all. See Order Types.
One exception worth knowing: Hyperliquid Vault copy trading places mirrored orders as market orders, so your fill price can differ from the Vault's. That is inherent to how mirroring works and is not adjustable.
Order partially filled — what happens next? Behavior depends on the order type:
- Market orders — the unfilled remainder is cancelled; the venue couldn't match it at acceptable prices.
- Limit orders — the unfilled remainder stays open at your limit price until filled, cancelled, or expired.
Check the order in its venue's order list (for stocks, Orders on your account page) — the filled quantity, remaining quantity, and current status are shown. To replace the remainder at a different price, cancel it and submit a new order.
What are the trading fees? Fees differ by venue. Stock orders carry no Alphio fee — you pay only what your broker charges. On Hyperliquid and Polymarket, Alphio earns a builder fee on each order, charged at execution. Tokens trades carry an Alphio service fee plus network costs. Orders on earlier KuCoin, Kraken and OKX connections are charged that exchange's own fees. Alphio does not take a share of your profits. The cost that applies to your order is shown before you confirm it. See Trading fees.
