Meridian Guard

The rules you set for yourself. Enforced automatically.

When you are calm, you define the rules you want your future self to follow. When the moment comes — losing streak, tilt, blown daily limit — Guard enforces them without requiring a decision from you.

Behavioral economists call this a commitment device — a mechanism you set up in advance to constrain your future behavior. Institutional traders have compliance systems that do this automatically. Meridian Guard does the same for independent traders.

Step 1 — Define when to intervene

6 Trigger conditions

Each rule fires once when the condition is entered, then resets. No repeated alerts, no micromanagement.

PSI Below

Psychological stability drops under a threshold you set.

Consecutive Losses

N losses in a row within the session.

Session P&L Below

Daily realized P&L falls below your limit.

Unrealized P&L Below

Open position floating loss exceeds threshold — before you close.

Single Trade Loss Exceeds

One trade loses more than a defined amount.

Session Time Over

You have been trading longer than you planned.

Step 2 — Choose what happens

5 Action levels

From a quiet nudge to a full broker disconnect. You pick the level that matches the severity of the rule.

L1 Toast

A quiet notification. Does not interrupt your flow.

L2 Acknowledge

Type your own pre-written phrase to continue trading.

L3 Countdown

Forced waiting timer. Cannot be skipped.

L4 Risk Alert Mode

Persistent banner. Every entry requires active confirmation.

L5 Disconnect

Disconnects your broker. Your positions are never closed by the system.

Why L2 is the most powerful level

You write the phrase yourself — when you are calm, before the session starts. In the moment, you have to type it to continue. Something like: "I will not revenge trade. My plan is my edge."

Typed in your own words, at the exact moment you need to hear them most.
