| Daily / max drawdown | Independent bases: trail, static, equity, pip/absolute, weekly. Warning rungs before hard breach. Optional grace window. | Flatten rest of day, or fail |
| News window | Mapped event, independent pre/post minutes, instrument map (USD release need not lock GBP). Hold-through is a separate class — no double-count vs drawdown. | Reject / flag / flatten |
| Weekend / session | Friday cut-off with symbol exceptions; London / NY / Asia / custom windows. Thin-session harvesting is a policy, not a vibe. | Flatten or block new |
| Min / max hold | Cannot close before N seconds (per symbol group). Force-close after a duration on funded books that should not carry a hedge forever. | Flag / HFT score / flatten |
| HFT burst | Rolling 1 / 5 / 60 minute frequency caps plus tick-scalp repeats. Score decays so one fast session does not brand the account forever. | Block / review |
| Latency arb | Fill vs mark (or LP) timestamp gap. Hit-rate over a window — not one lucky fill. Especially on CFDs. | Block |
| Martingale / averaging | Classic 2×, Fibonacci, fuzzy 1.8× / 2.1×, and adds to a loser without a clean double. Cross-session and cross-symbol lookback. | Reject the next add |
| Grid geometry | Equidistant pending cluster (typically 5+ workings), bi-directional “hedge” grids, max concurrent per symbol and direction. Caught before they fill. | Flag / reject |
| Copy / hedge pair | Timing, instrument, side, size overlap. Opposite-side pairs on the same tick. Evidence pack: fills, identity, timeline. | Review / payout hold / lock |
| VPN / TOR / geo | Path class (VPN, proxy, TOR, datacenter vs residential), declared KYC vs resolved geo, shared-IP farms, device/terminal ID across logins. | Warn, case, or block |
| Size / instrument | Max lot, min size, aggregate exposure, single-symbol concentration, allow/deny lists, per-symbol caps on the names they actually blow up. | Reject at the gate |
| EA / target games | Algo policy per program; stop/swap abuse; one-tick scalp into a pass; correlated hedges; overnight gap lottery. Logged as its own class. | Flag or fail |
