A free, fully open Nikkei 225 EA. It buys when price is leaning up, momentum isn't stretched and volume is unusually quiet, then closes all positions by 17:00 server time. The EA employs three conditions, operates on a long-only basis, executes one trade at a time, and includes a stop loss on every trade.

Strategy Details

A trading signal is generated when all three conditions are met on the bar that just closed:

1. Price Lean: The closing price is more than half a standard deviation above its 34-bar average.

2. Momentum Check: The MACD histogram, measured in ATR units, is below 0.2. This condition filters out strong upward price surges.

3. Volume Condition: Tick volume is below 60% of the normal volume for that specific time of day (calculated using the average of the last 20 days).

These conditions were identified through automated research. The code is provided openly for users to test and evaluate without theoretical claims about their underlying mechanism.

Trade Management:
The EA enters a long position at the open of the next bar. It implements a stop loss set at 4 ATR and a take profit target at 3.5 ATR. All open positions are closed by 17:00 server time. In the backtest, 63% of trades were closed at the 17:00 server time close, 26% reached the take profit target, and 11% were closed by the stop loss.

Trading Schedule:
Trades are taken from Monday to Friday, with signals identified between 11:00 and 14:59 server time, resulting in entries between 11:15 and 15:00 server time, after the Tokyo cash session closes. The times below assume a MetaTrader server time of GMT+2 in winter and GMT+3 in summer:

Entry Window
Close Time
Server Time
11:15 to 15:00
17:00
New York Time
04:15 to 08:00
10:00
London Time
09:15 to 13:00
15:00
UTC
08:15 to 12:00 (summer), 09:15 to 13:00 (winter)
14:00 (summer), 15:00 (winter)

If your broker utilizes a different server time, adjust the trading hours accordingly. The EA will display your server's GMT offset upon initialization.

Setup Instructions:
Attach the EA to your broker's Nikkei 225 chart (e.g., JPN225, JP225, NIKKEI225) on the M15 timeframe. Lot size is the primary adjustable setting. Thresholds and trading hours are available as inputs for experimentation. The validation section at the bottom of the source code is solely for MQL5's automatic testing and does not affect live trading on JPN225 M15.

Advantages and Disadvantages

Advantages

- Three clear and understandable conditions implemented in readable code.
- Profitable performance recorded in every calendar year tested.
- Successfully passed 15 stress tests.
- Every trade includes a stop loss, and all positions are closed by 17:00 (eliminating overnight risk and swap fees).
- Free to use, with complete source code provided.

Disadvantages

- Long-only strategy, which may result in periods with no trading activity.
- Fixed lot sizing means the dollar risk increases as the index value rises (average trade value increased from approximately $92 in 2022 to $256 in 2026).
- The volume condition relies on tick volume, which can vary depending on the broker's data feed.
- Limited to a single market (Nikkei 225) and timeframe (M15).
