About ChallengeScalMorning_S_CHFJPY

ChallengeScalMorning_S_CHFJPY is an EA in the CSMS (ChallengeScalMorning_S) series, developed based on the CSMSV (ChallengeScalMorning_V) series, which has over six years of live account forward-testing results. In the CSMS series, logic is optimized for each currency pair, and this EA uses a trade logic tailored specifically for CHFJPY. ChallengeScalMorning_S_CHFJPY is a short-term, fast-paced scalping EA that trades to capture liquidity restoration in the early hours of Japan time. It enters in the early JST hours and aims for price movement around the start of the Tokyo market.  
 

Features

① Entry in the long-term trend direction with three entry logics

An EA that targets pullbacks and retracements in the medium-to-long-term trend direction. It integrates trend determination logic with three entry logics using multiple indicators.  

② Small losses, large profits

Many morning scalper EAs prioritize win rate, but the CSMS seriesaims for average profit > average loss, i.e., a small-loss, large-profit design.

Note that this EA sets a relatively wide maximum stop loss, but the actual average loss at 0.1 lots is about -9.03 USD (about -9.0 pips), so most trades end with small losses.  

③ Logic targeting morning liquidity recovery

The early Japanese morning is a period of low liquidity where short-term pullbacks or retracements toward the trend direction are likely. This EA enters on pullbacks and retracements during this time to target price moves after the Tokyo market opens. Also, liquidity in the early JST morning can widen spreads depending on the broker. In winter time spreads widen around 7:00–8:00, and in summer time around 6:00–7:00; during these times, entries may be avoided or the number of entries may be significantly reduced. This is not an abnormality; it is a setting to avoid trading when spreads widen. Entries tend to increase around the periods before and after spread widening.  

④ Short-term, decision-focused EA

This EA is not ultra-short-term scalping to close in minutes, but a \"short-term, decision-focused\" EA that closes positions after holding for a few hours.Short-term, decision-focused EAIt enters in the early morning and closes the position in under five hours, typically by around 9:50 AM JST.

 

⑤ Based on a long-running predecessor

⑥ Optimized for each currency pair

In the CSMS series that emphasizes compatibility with each currency pair without over-optimizing, optimization is performed per currency pair.  

⑦ Compounding feature

Equipped with a compound interest feature. Orders are placed using the portion of excess margin specified as a percentage (risk value).

Q&A

QPlease recommend a securities company or broker. ABecause the EA enters in the early JST morning, brokers that excessively widen CHFJPY spreads in the early morning may trigger stop losses. We do not recommend them. Prefer brokers with narrow spreads that do not widen too much in the early morning.   QCan I run this on currencies other than CHFJPY? AThis EA is CHFJPY-specific and cannot be used on other currency pairs.   QCould you share more details of the logic? ASorry, but the details of the logic are not disclosed.   QWill it surely be profitable? ANot guaranteed. If the market conditions do not fit the logic, losses may occur. Therefore, profits are not guaranteed, and losses can occur as well.   QCan I run it together with other EAs? AYes. However, if the magic numbers are the same, please change them to avoid conflicts.   QIs it okay to run it continuously? AThe EA is designed to operate for long periods, but drawdown might increase or stagnate. If such conditions occur, continuing to run may enlarge losses, so judge operation based on drawdown, acceptable loss, and other criteria.   QIs a VPS required? AA VPS is not mandatory but is recommended for stable operation.   QWhat is the average holding time? AThe average holding time is a few hours, with trades typically closed by around 9:50 AM on the same day.
