Auto runs on the server, also when the page is closed. It watches the order books of both legs and sends a chunk whenever the net spread for that chunk size, fees included, is at or above your threshold, until the whole amount is filled.

​
Opening

  1. Choose Open › Auto on the spread page.
  2. Enter the size, Min In, %, and for perpetual legs Leverage and Margin.
  3. Click Start.
The panel shows Filled, Fillable now (the size the books allow at Min In right now), In avg, In now, Chunks and Missed. The status is Running, Waiting, Paused, Done or Stopped, with a note such as waiting for In ≥ N, depth at Min In is below the exchange minimum, waiting for order books, lot steps of the legs do not match, rate limit — next chunk shortly or evening legs.

​

Auto is running on this pair — pause it first appears when you try Semi or Manual on a pair with a running Auto. One Auto per pair, at most 3 active Auto runs per account.

Chunk orders

Chunks are market orders or IOC limit orders, chosen in Settings › Trade, see Trade settings. With IOC a leg may fill partly, Auto then evens the legs: completing the lagging leg or rolling back the leading leg. All runs are listed in Tools › Positions › Auto with Pause, Resume, Stop and Pause all, see Positions.
