Allocate equal budgets across prices
For N levels, the arithmetic spacing is (upper price − lower price) ÷ (N − 1). The first level is the lower endpoint and the last is the upper endpoint. Each receives budget B ÷ N, where B is the total quote amount. At price P with entry fee rate c, quantity is (B ÷ N) ÷ [P × (1 + c)]. Lower prices therefore buy more units; equal quote budgets do not create equal base-asset quantities.
Inspect combined entry and stop exposure
Total acquired quantity is the sum of the planned quantities. The all-in average acquisition cost is the full budget divided by those units, including modeled entry fees. The all-filled stop scenario sells that same quantity at the entered stop fill, deducts the separate stop-exit fee and compares net proceeds with total spending. This is a planned execution-price assumption rather than a stop-trigger guarantee. Adverse slippage beyond the chosen stop fill would increase the actual loss.
Separate a plan from a fill sequence
A ladder can fill partially, remain untouched or fill completely during a rapid decline. The all-filled scenario is not a probability estimate. Recalculate with only the orders that actually filled when evaluating an existing position. Exchange tick sizes, quantity steps and minimum order values can require changes to individual rows. Available balances can also be reduced by other open orders. This local planner neither reserves funds nor submits or monitors stop orders; save its output as a proposed allocation for independent review.
