Feature
Adaptive Learning & Settings
Every trader has a different normal. A scalper and a swing trader should not be measured by the same yardstick. Meridian starts with the rules and boundaries you set, then learns from your actual sessions — so feedback gets more accurate as your history grows, not more generic.
Adaptive learning and settings walkthrough
See how profile settings define your trading structure and how the adaptive baseline updates as sessions accumulate.
Two layers. One system.
Settings define the structure. Baseline learning makes it personal.
Layer 1
Profile settings
You declare your session window, typical size, entry frequency, stop conventions, and risk limits. Before you have trading history, these give Meridian a starting point calibrated to your style.
Layer 2
Adaptive baseline learning
After each session, Meridian updates what it knows about how you actually trade — size, hold time, loss magnitude, entry pace. As sessions accumulate, observed behavior gradually replaces the declared settings as the reference point.
What you configure
Your profile covers the shape of how you trade and the rules you hold yourself to.
Session & schedule
- ✓Trading window start and end time
- ✓Session window check can be disabled for traders without a fixed schedule
Size & frequency
- ✓Normal position size range (min and max contracts)
- ✓Expected trades per session (min and max)
- ✓Typical rest time between trades
Risk limits
- ✓Maximum stop-loss width in ticks
- ✓Maximum daily loss in USD (optional)
- ✓Maximum losing-trade hold time
- ✓Pause-after-N-losses rule
- ✓No stop-loss trader mode (suppresses naked position detection)
Sensitivity & weights
- ✓Three sensitivity presets: Conservative, Balanced, Aggressive
- ✓Individual weight for each of the seven behavioral signals
- ✓Recovery speed multiplier
Account selection & test mode
- ✓Choose which accounts Meridian monitors, or monitor all by default
- ✓Exclude automated strategy fills from PSI and baseline
- ✓Test Mode: PSI runs live but nothing is written to baseline history
- ✓Market Replay sessions are automatically excluded from baseline learning
Early profile vs. a mature one
Early sessions
Your declared settings do most of the work. The system is more lenient because it does not yet have enough data to be precise about what is normal for you.
After ~30 sessions
The baseline has enough history to reflect your real behavior. Thresholds sharpen because the system knows your actual patterns — not just what you declared at setup.
If your style changes, no manual reset is needed. The baseline evolves with each session and shifts naturally toward your new behavior over time.
Sensitivity presets
Controls how quickly PSI responds to behavioral pressure, independent of baseline learning.
Conservative
Earlier warnings, faster drops, slower recovery. More frequent alerts in exchange for catching pressure sooner.
Balanced default
Catches meaningful behavioral drift without firing on routine variation. The right starting point for most traders.
Aggressive
Higher thresholds, requires more extreme behavior to move PSI. For disciplined traders who want signals reserved for genuine outliers.
Stop mistakes before they reach the order window.
Meridian adapts to your trading style over time — fewer false signals, sharper feedback as your baseline matures.
