Nexus Trade Terminal

Nexus Trade Terminal is a utility Expert Advisor that combines market context and manual execution on one panel. On every closed bar it updates three readings and offers buttons to send orders. Panel execution is disabled until you allow it in the inputs.

How it works

• Regime: Hurst exponent and fractal dimension over the lookback window, plus momentum and volatility, classify the market as trend, mean reversion, chaotic or range/accumulation, with a heuristic confidence value.
• Volume and gap monitor: flags the last closed bar as a large volume cluster when a three-candle price gap is present and the Z-score of tick volume (adjusted by spread) reaches the threshold.
• Pair reading: Z-score of the price ratio between the chart symbol and a second symbol, plus the correlation of their bar-to-bar changes.

Panel buttons (require InpAllowExecution = true)

• BUY / SELL: market order sized by risk percent, with the default stop loss
• RESCUE: if the EA's basket loss reaches the trigger, opens an opposite position equal to the net exposure (hedging accounts only)
• STAT-ARB: if the pair Z-score is beyond the entry level, sells the relatively high leg and buys the low leg at the base lot, each with an optional ATR(14) stop
• CLOSE ALL: closes all positions with the EA's magic number on any symbol

Pair leg management

Pair legs opened from the panel are closed together automatically when |Z| falls below the exit level (0 = off), and if one leg is closed, the other is closed too.

Live trading disclosure

The EA never opens a position by itself in live trading; every order comes from a button, and buttons do nothing while InpAllowExecution is false (default). Its only automatic action is closing pair legs as described above.

Strategy Tester

As the panel is manual, InpTesterAutoDemo (default true) opens demonstration trades in the Strategy Tester only: one position at a time, direction from 10-bar momentum, risk-based volume, default stop, target at twice the stop. It never runs outside the tester.

Inputs

• Regime lookback; flow lookback and Z threshold
• Risk %, default stop, rescue trigger
• Second symbol, pair lookback, entry Z, exit Z, base lot, leg ATR stop
• Allow execution, magic number, tester auto demo

Notes and limitations

• The second symbol must exist at your broker with the exact name, otherwise the pair module stays idle.
• Trading involves risk; test on a demo account first.
