Reopen Book US100

Reopen Book US100 trades a Nasdaq 100 index CFD (US100, NAS100, USTEC and similar) with three independent modules on one chart. Each module has its own magic number, its own position and its own stop loss. There is no grid, no martingale and no averaging down, and no position is held over the weekend.

The three modules

• Reopen module. Trades the 18:00 New York reopen: a long on Sunday and a short on Monday, with one re-entry on Monday after a full stop. Positions are closed by 10:30 New York time the next morning.
• Asia module. A VWAP pullback in the New York evening (21:45 to 02:00), in the direction of the session VWAP, with momentum, efficiency and MACD filters. Everything is closed at 03:25. This module takes small targets against a wider stop, so it wins often and its losses are larger than its wins.
• ORB module. One opening-range breakout per day in the New York session, only in the direction given by where the session opens inside the overnight range. Stop from the daily ATR, target at three times the stop, time exit at 15:30.

Risk and account limits

• Position size is a risk percent of the balance per trade by default (0.7 / 0.5 / 1.0 percent for the three modules), so the EA sizes itself to the account. Fixed lots are available as an alternative.
• Lots are rounded down to the broker's lot step. On small accounts the minimum lot can be larger than the risk setting; check the lot sizes in the Strategy Tester on your own account size first.
• Optional limits in percent of the account size: maximum open risk in one direction, daily loss limit, daily stop that closes all trades, and a trailing drawdown limit. They are off by default and are meant for funded accounts.
• Margin, volume limits and the broker's stops level are checked before every order.

Setup

• Attach to one chart of your broker's Nasdaq 100 CFD. The chart timeframe does not matter; the EA reads M1 and M5 bars itself.
• Live, the EA detects the server time zone. In the Strategy Tester set "Server UTC offset in winter" and "Server daylight saving rule" for your broker, otherwise the sessions are shifted.
• A hedging account is recommended. On a netting account the modules take turns: a module waits while another one is in a trade.
• All stops and targets are a percent of the price, so they follow the index level.

Inputs

The inputs are grouped as in the Inputs tab. Stops, targets and triggers are a percent of the price.

• General: magic number, position sizing (fixed lots or risk percent of the balance), optional CSV log of closed trades.
• Broker clock: automatic detection of the server time zone, server UTC offset in winter, daylight saving rule (United States, Europe or none).
• Account limits, in percent of the account size, 0 = off: account size, maximum stop risk open in one direction, daily loss limit, daily stop, trailing drawdown limit, safety distance, clock and hour of the daily reset.
• Reopen module: switches for the Sunday long, the Monday short and the Monday re-entry, lots or risk per trade, maximum spread, closing time, stop loss, breakeven, take profit and trailing stop.
• Asia module: module and night switches, lots or risk per trade, entry window and closing time, maximum trades and losses per session, long and short switches, take profit, stop loss, breakeven and trailing stop for each side, reversal trade, minimum VWAP slope, widest signal candle, filter switches.
• ORB module: module switch, lots or risk per trade, stop as a share of the daily ATR, take profit as a multiple of the stop, minimum ADX, time exit.

What to know before buying

• The settings were developed on 2024 to 2026 data, a period of high volatility for the index. In tests on earlier years two of the three modules were flat or negative. Results depend on the market regime.
• The Asia module uses tick volume for its VWAP, so signals differ between brokers.
• Spread at the 18:00 reopen matters for the Reopen module. A maximum-spread input is provided.
