The merchant balance endpoint provides an estimate of the available funds in the merchant account on a specified target date. It takes into account the scheduled merchant transactions in the specified marketplace to calculate the estimated values.

estimated_available_amount represents the forecasted amount that might be available to the merchant on the target date, based on the current scheduled transactions. This estimate is subject to change due to cancellations, new transactions, and advancements made by the merchant until the target date arrives.

If the merchant's scheduled balance is negative, the amount accumulates in the scheduled_amount field until it becomes positive and is available for settlement. Therefore, a negative scheduled_amount is not considered for settlement until it turns positive.
