Behavioral signals
What Meridian watches for
Seven behaviors that appear before a trader breaks the plan — calibrated to your own baseline, sharper the more you trade.
Revenge Entry
Re-entering too quickly after a loss.
Stop Manipulation
Widening or moving your stop when the trade moves against you.
Size Spike
Position size exceeding your declared rule — heavier weight during losing streaks.
Rushed Exit
Cutting a profitable position before any meaningful price move — the "cut winners" pattern.
Position Overstay
Holding a losing trade past your historical tolerance — the "let losers run" pattern.
Rule Violations
Trading outside the rules you set in your own profile.
Overtrading Pace
Entry frequency accelerating past your normal session rhythm.
Make discipline measurable.
For the first time, see what your discipline is actually costing you — composure grades, weekday patterns, and the PnL impact of every behavioral slip. Journals show what happened. Meridian shows why, and what to do next.

We are not a better risk tool.
We are a different stage.
Every other risk tool acts after the breach in discipline — but why?

Meridian is a different category — a behavioral leading indicator that fires before any hard limit would need to. The first tool that makes trading discipline measurable in real time.
You write the rules. Guard enforces them.
Willpower is not a risk strategy. Guard acts as your personal compliance system, helping stop mistakes before they happen — with alerts, typed acknowledgments, countdowns, confirmation-required mode, and broker disconnect.
What traders say
From early access users
"Passed my third Apex evaluation. The first two I blew up on days where, in hindsight, I should have just closed the platform. The pattern was obvious once I could see it."
Anonymous
Prop firm trader
"Three months in. I thought I had clean execution — the overtrading metric disagreed from day one."
Anonymous
Futures day trader
"Turned out I wasn't losing because of my entries. I was adding to losing positions and ignoring my own rules. Took data to admit it."
Anonymous
"After a losing session I used to review charts to explain what happened. Now I check the session report first. It's faster and more honest."
Anonymous
ES / NQ
"It gives you the option to automatically close your positions, or you can choose to handle that part yourself. I stopped pretending I didn't notice the score dropping while I was moving my stop around."
Anonymous
NQ futures
"The seven bars make it immediately clear which habit is pulling the score down. I kept telling myself I was trading fine. The data disagreed consistently."
Anonymous
MNQ scalper
"I don't use tools that send my fill data to the cloud. Local-only was non-negotiable for me."
Anonymous
Independent trader
"Being able to use Market Replay without it touching my live baseline was more useful than I expected."
Anonymous
Futures swing
"I run two accounts with copy fills. I was expecting double-counting issues in the score. It handled it cleanly without any configuration."
Anonymous
Multi-account
"Post-session journals have their place. This is different — the feedback arrives while the session is still running, not the next morning."
Anonymous
"The stop-widening flag caught me doing something I always denied — moving my stop out when a trade went against me. Useful confirmation, even if it wasn't comfortable."
Anonymous
CL / GC
"I've restarted funded accounts more times than I want to count. If someone had told me a revenge-entry detector would matter more than another indicator, I wouldn't have believed them."

Prop trader
"Four years trading NQ. Thought I had a solid read on my own behavior. First week of data showed me I had several habits I wasn't aware of."
Anonymous
Day trader
"The caution signal fired and I decided I could manage through it. Twenty minutes later I had hit my daily limit. I can't blame the tool — I ignored it."
Anonymous
ES trader
"A rough Tuesday doesn't disappear from the score just because Wednesday started. That's accurate. That's how it actually feels."

Overnight + day
"Thought my exits were disciplined. Turns out there's a consistent pattern on certain days. I don't love it, but I can work with the information."

Index futures
"The alerts are infrequent enough that I don't tune them out. When one fires, I actually pause before doing anything."
