Core idea
Discipline first. Automation second. Risk controls always.
Quantum Bridge Management was built around a simple premise: short-horizon trading should be governed by defined rules, systematic execution, and repeatable risk controls rather than emotion, impulse, or discretionary market calls.
Photon Capital Fund LP applies this philosophy through proprietary quantitative models that analyze real-time market data and seek to identify short-term directional biases over intraday holding periods.
Intraday discipline
The strategy is designed to close positions before the end of each trading session and not maintain overnight exposure.
Embedded risk controls
Risk controls include position sizing thresholds, stop-loss placement, daily drawdown limits, and model-based exposure constraints.
Private fund
Photon Capital Fund LP
Photon Capital Fund LP is a Delaware limited partnership organized to operate as a private investment partnership. Interests are offered only to eligible investors, including accredited investors, subject to the fund’s governing documents and the General Partner’s acceptance.
