Position Reset

The "position reset" functionality in the TT system provides a seamless 24-hour trading period that automatically resets with the exchange session roll times or at a specific time defined by an administrator. At position reset time per trading day, fills from the previous trading day are removed from the order book and optionally turned into start-of-day (SOD) records that are priced at settlement.

Note: The position reset functionality in TT calculates a user's position in an account based on the fills for the exchange session that has already closed, and not for fills that occur in trading sessions after that time. If using a position reset override, TT recommends setting the position reset time after the close of the last exchange trading session for an account.

How Position Reset Works

By default, new accounts reset positions in each market at each market's session roll time (as set by TT). For example, at 16:37 CST, CME product positions are reset, and at 17:30 CST ICE product positions are reset. This default mode allows users to trade multiple markets without having to worry about setting a single reset time. Additionally, administrators can choose to override the default position reset time by selecting a time and timezone that applies to all accounts in the hierarchy. This allows administrators to choose a specific time to reset, typically because the company resets the account credit setting daily after marking to market.

For accounts at the beginning of a TT Session, "available credit" is set to the account-level Daily Limit setting. If the account has Create start-of-day (SOD) records checked, then any positions from the previous exchange session are converted to SOD records and priced at Settlement. If the account has Create start-of-day (SOD) records unchecked, positions from the previous session are not included.

The Create start-of-day (SOD) records setting is enforced per account regardless of the account hierarchy. If only the parent account has SODs enabled, then SODs from the child account still appear as part of the parent position. If child accounts should also generate SOD records, then as an administrator you can can enable Create start-of-day (SOD) records for these accounts.

Position Reset Times per Exchange

Note: When using Position Reset override, it's a best practice to set the account position reset to occur after the reset times listed below. If using an override, parent and child accounts need to be set to the same position reset time.
