Stop-defined share count on a clustered intraday short

The entry bar fixed per-share risk

The illustrated five-minute short was triggered when a red bar undercut the prior green bar at 37.54. The breakdown-bar trigger is used here only to locate the stop: a red bar that undercuts the prior green bar after a short pullback into declining moving averages.

A stop-loss was placed one cent above that entry bar at 37.70. That protective price sat a small increment beyond the entry bar so per-share risk was fixed at 16 cents before any size was chosen.

Cash risk became a rounded lot

Volatility position sizing in the case meant turning a pre-set cash-risk budget and the live stop distance created by the entry bar into a share count, then reducing that count so friction stayed inside the budget. An example cash-risk budget of 100 units against the 16-cent stop produced 630 shares. Even-lot rounding then cut the calculated count to a 600-share even lot so slippage and costs would not consume the planned cash risk.

The share count was derived from the planned cash risk and the stop distance. It was not derived from conviction, and it was not derived from how many names were breaking down.

The target was a multiple of the stop

Once the stop was known, the case used a planned minimum reward of three times the 16-cent risk as the target frame. That risk-reward ratio stated the planned target distance as a multiple of the initial stop width, and it was set before the position was managed.

Matching shorts stacked the open

Several other names printed the same short pattern on that open, so exposure also depended on how many look-alike setups were accepted. Clustered-setup exposure is the extra account risk created when several names print the same pattern and invite several similar positions at once. The case treated stacking too many of those matching shorts as a way to become overleveraged if the open reversed.

How TradersWeek reads the case

Editorial note. The archive records a historical workflow in which the stop came first, the lot was rounded down, the target was framed as three times that stop, and matching shorts on the same open were treated as stacked exposure. The two-step audit above is a TradersWeek reading of that workflow, not a claim made by the archive.
