Prop Firm Live Daily Breach Line: Accurate Drawdown Monitoring

Related: Prop Firm Guard Panel - another powerful indicator for MetaTrader 5 traders.

Prop Firm Live Daily Breach Line is a lightweight chart indicator built for prop firm evaluations and funded accounts.

Also recommended: Daily Profit/Loss Percentage Overlay for Prop Firm Daily Loss Limits - similar indicator with strong performance on MetaTrader 5.

It tracks your remaining daily drawdown buffer in account currency and draws a dynamic horizontal line (Daily Breach Level) on the chart.
You can immediately see the exact price where your open net volume on the active symbol will hit the daily loss limit.

Simple tick-value calculators often drift on cross pairs or miss intraday commissions from closed trades.
To solve this, the indicator reconstructs your exact 00:00 server-time balance from today's deal history and uses a two-step OrderCalcProfit check so the breach price stays accurate across forex pairs, metals, and indices.



How It Works



00:00 Baseline Reconstruction (Entry and Exit Deals):
When InpManualStartBase is left at 0.0, the indicator reads today's deal history starting from 00:00 server time (iTime PERIOD_D1).
It reverses all realized profits, swaps, fees, and both entry (DEAL_ENTRY_IN) and exit (DEAL_ENTRY_OUT / INOUT / OUT_BY) commissions.
A 5-second history cache prevents chart lag during fast market ticks.

00:00 HWM Snapshot (Balance vs. Equity):
Supports both Balance Only and Higher of Balance or Equity (00:00 HWM) reset rules.
During the midnight rollover window, it locks a single terminal GlobalVariable snapshot so post-midnight equity spikes don't artificially push your daily floor higher.

OrderCalcProfit Price Calibration:
Calculates net open volume (Buy Lots minus Sell Lots) on the current chart while floating P/L from other symbols is already included in Account Equity.
After a first linear estimate, it validates the exact loss distance with MQL5's native OrderCalcProfit() function.
If you're flat, hedged, or your lot size is too small to hit the limit even at zero price, the line hides automatically and shows the current status on the panel.

iCustom() Buffers for Expert Advisors:
Provides two non-drawing buffers (DRAW_NONE) so your own EA can read the numbers directly without scanning chart objects: Buffer 0 returns the Breach Price on the active symbol (0.0 if flat or unreachable), and Buffer 1 returns the Remaining Daily Buffer in account currency ($).

DPI-Scaled Panel and Clean Removal:
Displays a compact dark-slate HUD in the top-right corner scaled via TERMINAL_SCREEN_DPI, restores your original chart settings, and deletes all PFLBL_ objects cleanly in OnDeinit().

Technical Scope
