The trade copier for running size across TradeDay accounts

TL;DR: TradeDay accounts trade through Tradovate and Rithmic-based platform stacks — Trading Floor connects both natively. One leader, every TradeDay account mirrored in ~42ms median (live proof), each with its own multiplier and a Daily-loss guardian set inside your account's limits.

How it works with TradeDay

Connect each login the way you already sign in — Tradovate-based accounts via OAuth in about 90 seconds (we never see those passwords); Rithmic-based credentials stored encrypted. Crown a leader (a TradeDay account, a personal account, or a TradingView strategy), set per-account sizing, and trade normally. Every mirror prints its measured latency in your Copy Log.

Built for eval discipline

• Daily-loss guardian: set it a cushion inside your account's limit — a breach auto-flattens that account and stops copying to it, before the firm's number.
• Daily-loss guardian + per-instrument contract caps, enforced before orders fire.
• Per-account isolation: one account's guardian never stops the rest of the floor.
• Know your line: check any account's live breach level with the free trailing drawdown calculator.
• Pause between evals: your configuration, journal and payout history wait for you.
