Order Problems and Slippage

Common causes of order problems and slippage.

Updated over 2 months ago

Common Order Problems

  • Service Outages – If a data provider like Rithmic experiences an outage, orders may be delayed, rejected, or fail to route entirely.

  • Insufficient Funds or Margin - If your account balance or buying power is too low, your broker may reject the order.

  • Prop Firm Rules – Some prop firms restrict order types, sizes, or trading times. Orders outside those rules may be blocked.


Common Causes of Slippage

  • Market Conditions - Fast-moving markets can result in slippage or missed fills. Limit orders may remain unfilled if the market never trades at your specified price. This is common during high-impact news events.

  • Fast-Moving Markets – Price can change before your order reaches the exchange.

  • Order Type – Market orders are most exposed to slippage since they fill at the best available price. Limit orders control the maximum price you’ll pay but may go unfilled.

  • Slippage with Copy Trading – When copy trading is enabled, the main account order is placed first. Copied accounts may fill at slightly different prices depending on market movement and available liquidity.

Note: Tradester only routes orders. Final execution, fills, and any slippage are determined by your broker, prop firm, and exchange conditions.
