Python Iceberg Orders for Gradual Buying and Selling

Summary

The document presents Python examples of buy-side and sell-side iceberg execution. An iceberg order divides a larger target into smaller limit orders, placing them in relation to the current bid or ask and a configured price depth. The scripts track account balances or holdings, submit randomized order sizes within configured limits, and monitor whether an order has filled. If the market moves sufficiently far from the resting price, the script cancels outstanding orders and recalculates a price for the next attempt.

The examples describe polling and order management rather than a full execution analysis. They include simulated trading screenshots but no quantitative comparison of market impact, fill rates, or slippage. Their behavior depends on exchange order and account data, parameter choices, and cancellation handling; the article itself cautions that the code is for learning and should be used carefully in live trading. It does not explain how to optimize parameters or assess execution quality.

Key ideas

• Iceberg execution splits a large target into smaller limit orders to moderate visible order size.
• The buy and sell examples place orders relative to the current bid or ask using a configured depth.
• Order sizes can vary randomly while remaining bounded by the target and available funds or holdings.
• The scripts cancel and reprice orders when market movement passes a configured threshold.
• The examples demonstrate order handling but do not provide quantitative execution results.
