Define acceptable slippage before sizing the trade
Choose a fictional maximum slippage, such as 0.5%, for the exercise. Use an order-book snapshot to calculate how much size could be sold before the average execution crosses that boundary.
Record the answer as executable size at normal depth, not as a permanent property of the asset.
Apply a stress multiplier
Now assume visible depth falls by 50% and spreads double. Recalculate the same exit. If the position would now require 2% slippage, the worksheet should show the stress consequence in pesos and as a percentage of the account.
Add an access failure scenario
Liquidity is useless if the trader cannot reach it. Add a separate field for venue outage, withdrawal suspension or network congestion. The response may involve diversification of operational routes or smaller exposure, but the worksheet should not assume an alternative venue is automatically available.
Completion check
Your final card should show normal executable size, stress executable size, expected slippage, stress slippage and the condition that makes the proposed position too large for the exit plan.
