Margin Usage Timeline
The terminal's own Account tab shows used margin right now, but not whether it has been climbing steadily over the session or spiked briefly and recovered. This indicator samples AccountMargin() and AccountEquity() on a timer, plots margin used as a percentage of equity as a simple line, and draws two configurable level lines - a warning level and a critical level - so a trend toward over-leverage is visible before it becomes an emergency. An optional single Alert fires the first time usage crosses the critical level, re-arming only once usage has dropped back below the warning level, so it does not spam on every tick spent above it. Notes and limitations Like every "recorder"-style MQL4 indicator, only the current (rightmost) bar is ever written; earlier bars keep whatever value was last written while they were current. History before the indicator was attached shows nothing, since MQL4 keeps no record of past margin usage to backfill from. This measures used margin against equity, not the broker's own margin-level formula (equity/margin), which some brokers vary slightly (e.g. how hedged positions are netted for margin purposes) - treat this as a consistent internal trend indicator, not a byte-exact reproduction of the broker's own stop-out math.
