FAQ
PropLock currently works exclusively with NinjaTrader 8 on Windows. Our desktop agent syncs your trade data from NinjaTrader throughout the trading day.
We currently support Apex Trader Funding with all three program types: EOD (End-of-Day trailing), Intraday (real-time trailing), and Legacy (pre-March 2026) accounts. More prop firms coming soon.
For evaluations we track: profit target progress, trailing drawdown (EOD or Intraday), daily loss limit (where applicable), max contracts, time countdown (30 days for new accounts), and qualifying days.
For PA accounts we track: Safety Net status, trailing drawdown, daily loss limit, consistency rule (50% for new, 30% for legacy), payout eligibility, payout caps, contract scaling tiers, and inactivity rules.
No. We only receive data for closed positions from NinjaTrader. This means if your equity peaks intraday and drops, we cannot track that high watermark. Always maintain your own buffer and monitor your platform for real-time compliance.
Unlimited. Connect as many evaluations and funded accounts as you want. Each account can have its own program type and individual rule settings. Track everything from one dashboard.
Let PropLock monitor your compliance so you can focus on trading.
