🦖 T-Rex Risk Guardian

Your account level T-Rex that protects balance, equity and prop rules

T-Rex Risk Guardian Lite is not a trading strategy. It does not open trades. It sits on top of your manual trading and any cBots you run and enforces your risk rules with zero emotions.

It watches daily and weekly drawdown, blocks overtrading, closes positions when limits are breached and gives you a clear HUD that shows how close you are to your limits.

Attach T-Rex to any chart on your account and it will start monitoring all symbols and all trades. If you want, it can limit its scope to labeled strategies only.

✅ Key features

  • Daily loss and profit limits
    Define daily loss and profit targets as a percentage of your starting equity for the day. Once your daily drawdown or profit target is hit, T-Rex locks the account logic according to your settings.
  • Weekly limits like a prop firm
    Enable Weekly Limits and set a Weekly Loss Limit and Weekly Profit Target based on your starting equity for the week. The bot tracks closed trades for the week and will not let you exceed your weekly rules.
  • Global equity floor
    Equity Floor Drawdown Percent defines a maximum account wide drawdown from the equity level when the bot started. If equity falls below this level, T-Rex triggers an emergency lock.
  • Prop Mode with high watermark daily DD
    In Prop Mode you can use high watermark logic so daily drawdown is calculated from the highest equity reached during the day, not just the opening equity. This mimics how many prop firms define daily DD.
  • Overtrading control
    Max Trades Per Day caps how many trades you can open in a single day. Max Losing Trades in Row stops you after too many consecutive losing trades.
  • Manual versus cBot scope
    Include Manual Trades controls whether T-Rex tracks every trade on the account or only trades that have a Label, for example cBots or specific strategies.
  • Two lock behavior modes
    Lock Action:
    • BlockNewTrades blocks new trades while leaving current positions alone
    • CloseAndBlock closes all open positions, cancels all pending orders, then blocks new trades for the lock duration
  • Time based lock logic
    Lock Duration Mode:
    • UntilEndOfDay keeps the account locked until the next trading day
  • On chart HUD in two modes
    • Compact shows the essentials: Balance, Equity, daily PnL, weekly PnL, room to limits, trades and time to reset
    • Advanced shows PnL decomposition, daily and weekly DD, usage of Daily Weekly Overall limits, last lock reason and the scope of trades being tracked
  • Risk color coding
    HUD color changes based on how much of your limits you have already used. Green when risk usage is low, yellow when it approaches the middle zone, red when risk is high or the account is locked.
  • Custom HUD colors
    HUD Color Active, Warning and Locked let you adjust the panel colors to fit your chart theme or dark mode.
  • Status sound alerts
    Play Status Alert plays a sound when a new lock is activated and when it expires. You do not have to stare at the chart to know your guardian stepped in.

🎯 Perfect for:

  • Prop firm accounts with strict daily and overall drawdown rules
  • Grid and high frequency strategies that need a strong leash
  • Discretionary traders who tend to overtrade or revenge trade

T-Rex Risk Guardian – Parameters Overview

Daily Limits group

Daily Loss Limit Percent
Maximum allowed daily drawdown as a percentage of your starting equity for the current day. When daily drawdown in percent reaches or exceeds this value, T-Rex triggers a lock. In Prop Mode with high watermark, daily drawdown is measured from the highest equity reached during the day.

Daily Profit Target Percent
Daily profit target as a percentage of your starting equity for the day. When daily PnL in percent reaches or exceeds this value, the bot treats the day as complete and can lock trading until the next reset.

Daily Reset Time (HH:mm)
The time of day when a new trading day starts for statistics. You can align this with your prop firm session or your own trading session. All daily PnL and DD calculations are made within this window.

Weekly Limits group

Enable Weekly Limits
Enables or disables weekly limits. If false, no weekly loss or profit targets are used to trigger locks.

Weekly Loss Limit Percent
Maximum weekly drawdown in percent based on the equity at the start of the week. This is based on closed trades only. If the weekly PnL in percent goes below minus this threshold, T-Rex will lock trading.

Weekly Profit Target Percent
Weekly profit target in percent, based on starting equity for the week. Once reached, the bot may lock trading for the rest of the week, depending on your lock settings.

Week Start Day
The first day of your trading week for calculations, for example Monday. The bot builds the weekly window using this day and the Daily Reset Time.

Trading Control group

Max Trades Per Day
Maximum number of trades you are allowed to open in one trading day. Each new position increments this counter. After the limit is reached, new trades are blocked until the next day.

Max Losing Trades in Row
Maximum number of losing trades in a row allowed. When this number of consecutive losing trades is reached, T-Rex locks trading and stops you from digging the hole deeper.

Include Manual Trades
Controls the scope of trades:

  • true: include all trades on the account, including manual ones
  • false: include only trades and pending orders with a nonempty Label, for example specific cBots or strategies

Advanced Risk group

Use Floating PnL (Equity based)
Controls whether floating PnL is used in PnL calculations:

  • false: daily and weekly PnL are based on closed trades only
  • true: daily PnL uses closed trades plus floating PnL on positions opened today, weekly HUD shows floating PnL for all open positions

Daily DD is always measured using equity, not just closed PnL, but this setting affects how PnL in percent is displayed and how daily profit targets are evaluated.

Equity Floor Drawdown Percent
Global account drawdown limit in percent, based on equity at the time the bot started. If current equity drops more than this amount below the starting equity, an emergency lock is triggered. Set to 0 to disable this filter.

Prop Mode group

Prop Mode Enabled
Turns on prop firm oriented behavior. This makes daily DD handling stricter and focuses on protecting the account from rule breaches.

Use High Watermark Daily DD
Only relevant when Prop Mode is enabled. In this mode daily drawdown is calculated from the highest equity reached during the current day. This is similar to how many prop firms define their daily loss limits.

Lock Behavior group

Lock Action
Defines what happens when a limit is hit:

  • BlockNewTrades: block any new trades from opening, leave existing positions untouched
  • CloseAndBlock: close all open positions, cancel all pending orders and block new trades until the lock expires

Lock Duration Mode (hidden)
Defines how long a lock remains active: only one option as default: keep the account locked until the next trading day (invisible in parameters)

HUD group

HUD Mode
On chart panel mode:

  • Off: HUD is disabled
  • Compact: minimal display for quick daily monitoring
  • Advanced: full professional HUD with detailed statistics and lock information

Panel Corner
Corner of the chart where HUD text appears. Use this to avoid overlapping important price action or indicators.

HUD Color Active
Text color used when risk usage is low and the bot is active.

HUD Color Warning
Text color used when risk usage is in the mid range, for example above about 50 percent.

HUD Color Locked
Text color used when risk is high, when the account is locked or when DD usage is above the highest threshold.

Alerts group

Play Status Alert
If enabled, the bot plays a sound whenever a lock is activated or expires. This helps you notice that T-Rex has stepped in or has released the brakes.

How to use T-Rex Risk Guardian

    global max DD for the account, for example 10–15.
  • Prop Mode Enabled + Use High-Watermark Daily DD
    turn on if you trade a prop account and they use high watermark daily DD.

3. How to monitor the bot

  1. HUD on the chart
    • Header like:
      🦖🔒 T-REX RISK GUARDIAN: ACTIVE / LOCKED
    • Below: Balance / Equity, PnL today, DD, DD used, room to limits, trades, time to reset.
    • HUD color:
      • green – comfortable risk
      • yellow – limits partially used
      • red – high risk or lock.
  2. Sounds
    • With Play Status Alert enabled:
      • negative sound when LOCK is activated
      • positive sound when lock expires or a new day starts.
  3. Log / Journal
    • The bot prints why a lock happened, for example:
      Daily loss limit hit..., Weekly loss limit hit..., Equity floor reached..., Max trades per day hit...
    • You also see which positions were closed and which pending orders were cancelled.

Prop account

Goal: do not violate prop firm rules: daily DD, overall DD, weekly / phase targets.

Here we always adapt to the exact rules of your prop firm.

Example assumptions:

  • Max daily loss: 5%

  • Enable Weekly Limits: true
  • Weekly Loss Limit (%): 7.0–8.0

    • prop scalper: 20–30
    • prop intraday: 5–10
  • Max Losing Trades in Row: 3
  • Include Manual Trades: true
    Because prop rules are based on the whole account.
  • UseFloatingPnL: true
    Prop firms usually look at equity, not only closed trades.
  • Equity Floor Drawdown (%): 9.0–9.5
    Slightly inside their max overall DD.
  • Prop Mode Enabled: true
  • Use High-Watermark Daily DD: true
  • Lock Action: CloseAndBlock
    Better to stop everything before you hit the official limits.

HUD

Last lock reason.

HUD Mode: Advanced
On prop it is critical to see: Daily DD used, Weekly DD used, Overall DD used
