Trading isn't lost
in strategy. It's lost
in behavior.
Plan your trades, surface rule conflicts, and see what emotional execution actually costs.
$15.99/month or $119.99/year.
72% of your losses
came from rule-breaking trades.
Illustrative scenario, not a performance claim.
You followed your plan on 9 of 11 entries. Two violations between 10:50 — 11:10.
Built for discretionary intraday traders who already have a strategy —
but keep breaking execution rules.
Killzone-based execution. Displacement, CISD, liquidity events.
Topstep, FTMO, MyFundedFutures. Drawdown rules, daily caps.
Written setups, sizing limits, daily caps — broken under pressure.
Not built for swing traders, options sellers, or long-term investors.
Strategy doesn't lose money.
Execution does.
Overtrading, revenge entries, hesitation, sizing under emotion — behavior destroys consistency long before strategy does. Costante is built around that fact.
Behavior — overtrading, revenge entries, sizing under emotion — destroys consistency long before strategy does.
Journals record the mistake. Costante keeps written rules and decision context available for review. Read why trading journals fail rule-breakers.
- You said "last trade." You took five more.
- You lost once — then doubled size.
- Your setup wasn't there. You still entered.
- You wrote the rules. You ignored every one.
Five steps.
Run every session.
Not a feature collection. Costante sits around your existing trading day — before the session, during decision-making, and after the close. Plan, check, log, review, measure. The loop is the product.
Built for the moment before damage happens — not just review after it.
Plan
Set the day’s setups, risk caps, instruments, and stop-rules before the session starts. Costante keeps the plan visible when the session opens. Set setups, risk caps, and stop-rules before the session opens.
Check
Review an intended action against the written plan and applicable Session Guardrails before deciding how to proceed. Review an intended action against the plan and guardrails.
Log
Log entries, exits, screenshots, emotion, and rule status in seconds, so later review retains the relevant context. Log trade context and rule status in seconds.
Review
Close the session with a structured readout: where discipline held, where drift appeared, and what behavior cost you. Close the session with a structured readout of what behavior cost you.
Measure
Measure behavioral cost, discipline trends, and repeated drift without treating a trade outcome as proof of decision quality. Measure behavioral adherence and repeated drift over time.
A complete behavioral
operating layer.
A calm surface
for a chaotic job.
Three layers, one loop: planning before the session, checking intended actions during the session, and behavioral review after the close.
Entry violated your plan. You said only A+ setups — this one was C.
