Account Groups
Account Groups need to be created and attached to a harvest rule before opportunities will be generated. SMArtX will analyze lots and positions for potential opportunities across all accounts in the group, while guarding against wash sales.

Harvest Rules
Harvest Rules defines what will be considered an opportunity for each account group attached. Set specific criteria like minimum dollar threshold, percent of the account, a threshold for percentage gain/loss that triggers a harvest, as well as whether the rule applies to lots, positions, or both.
Select the Harvest Rules tab to view your current Harvest Rules in the list:
Select the 3 dot vertical icon at any rule
Use the drop-down to edit, assign, or remove as needed.
⚠️ Advisor-managed (APM) sleeves
Automatic replacement purchases and buybacks apply to model sleeves. For APM sleeves, rebalance after the harvest to buy the replacement, and rebalance again after the wash sale period ends to buy back the harvested symbol. Until you rebalance, harvest proceeds stay in cash.
Edit Advisor Group Rule or Create New in the Side Sheet
Set specific criteria:
Minimum dollar loss
Percent of the account
Threshold for percentage gain/loss that triggers a harvest
Adjust for Custodian Types — Select between applying rules against positions, lots, or both:
Positions — rules will look at the position level to determine if the objective can be met and return positions that meet the rule
Lots — rules will look at the lot level to determine if the objective can be met and return only those lots that apply
Positions and Lots — the rules will look at both positions and lots to determine if the objective can be met and return all data points that apply
Enable Default Replacement Securities:
The rule can be configured to auto-purchase a specific security when a loss is generated. If the scheduler is used, the replacement security will be sold and the model position repurchased following the wash sale period.
This setting applies across all accounts and positions tied to the rule, but you can edit it manually per trade if needed
Harvest Scheduler
With this automation, opportunities are generated, approved, and sent to market without manual review.
Select Scheduler On
Choose your start date
Select a recurring schedule using the Repeats dropdown
Decide how often each Account Group tied to a Harvest Rule is reviewed — monthly is a popular choice
If desired, choose a Default Replacement Security, which will be purchased in place of any loss, and automatically reversed following the wash sale period.
⚠️ Advisor-managed (APM) sleeves
The scheduler sends harvest sales for all sleeves, but replacement purchases and buybacks are automatic only in model sleeves. For APM sleeves, rebalance after each scheduled harvest to buy the replacement, and again after the wash sale period ends to buy back the harvested symbol.
Once complete, Review Side Sheet and Save Rule
