CVR-CA Single Pair EA

CVR-CA Single Pair EA is an Expert Advisor for a single instrument on MetaTrader 5. This EA is not designed to mechanically trade at fixed intervals; rather, it aims to check the relationship between trading costs and price fluctuation width and to suppress forced entries in markets with thin conditions. The basic structure is a DCA/TP based on the average entry price. In addition, it includes a CVR gate that compares costs, assumed slippage, spreads, and price movement ranges using ATR/σ. When conditions do not match, the design makes it easy to understand why it is waiting by displaying states such as WAIT / BLOCK / REJECT. This EA does not predict a specific market direction to profit; instead, it uses the volatility of the target instrument to aim for rotation via DCA and TP for a single-instrument EA. The backtests shown are conducted on the Nikkei 225. Recommended target: Nikkei 225 Backtest target: Nikkei 225 In addition, the performance of this EA depends not only on the instrument but also heavily on balance among margin amount, lot size, spread, volatility, and martingale (averaging) capacity. If the lot size is excessive relative to the account balance, sufficient rotation capacity may not be secured, and it may not operate as intended. When used with other instruments or other currency pairs, results with the same settings are not guaranteed. Always backtest in your own environment and confirm the balance between margin amount and lot size. Also, broker differences may apply to Nikkei 225 CFD symbol name, trading specifications, minimum lot size, required margin, spreads, and trading hours. Before use, be sure to check the specifications of the target instrument in your broker environment.

Losses may occur due to sudden market movements, widened spreads, order rejections, slippage, market halts, broker-specific differences, differences in historical data quality, setting errors, etc. Past Strategy Tester results do not guarantee future performance. Before live operation, be sure to verify behavior with Strategy Tester, a demo account, and small-scale operation. This EA is designed on the premise of sufficient margin capacity and appropriate lot settings. If the lot size is too large relative to the principal, it may not perform the DCA/TP rotation as expected due to unrealized losses or lack of available margin.
