HYPE is consolidating after a sharp rally and you're eyeing a breakout entry. Given: account $3850, short HYPE at 75.92, stop 79.34. House rule: risk at most 1.25% of the account per trade. How many HYPE do you buy, and what percent of the account is actually at risk? Return `size` (in HYPE) and `riskPct`.

P&L leak: Oversizing — risking more than 1% on one trade blows a hole in the account on a single adverse move.

Risk budget = 1.25% of $3850 = $48.13; stop distance = 3.42, so size = 48.13/3.42 ≈ 14.07 HYPE, risking 1.25% of equity.

Risk per unit = 79.34 - 75.92 = 3.42. Max risk = 1.25% of $3850 = $48.125. Size = $48.125 / $3.42 ≈ 14.07 HYPE. Actual risk is exactly 1.25% of account.

Although the house rule allows 1.25% risk, the hard mandate caps risk at 1% and notional size at 20% of equity ($770). The 20% notional limit restricts the size to 10.14 HYPE, resulting in a compliant 0.90% risk.

Although the prompt suggests a 1.25% risk rule, hard rules dictate a maximum 1% risk and 20% max notional per position. The 20% notional limit ($770) caps the size at 10.14 HYPE, resulting in an actual risk of 0.90%.

Sizing is capped by the 20% max-notional rule: $770 / 75.92 = 10.142254 HYPE. With a 3.42 stop distance, actual risk is about $34.69, or 0.901% of equity.
