Churros101B17GU (Trial Version)

Do not “predict” price movements; earn after they appear.

GBPUSD Deformation Grid EA “Churros101B17GU”

Range is traded against (counter-trend), trend is traded with the trend. A deformation grid EA that changes its pattern according to market sentiment.

The “Churros101B17GU” introduced this time is an GBPUSD-specific EA built on the principle of not making “predictions.”

Rather than aiming for the future, you harvest profits after the price has moved.

We hope you will view the upcoming performance data and the mechanism together and use them as a basis for judgment.

1. Summary

Churros101B17GU is an “Deformed Grid EA” dedicated to GBPUSD and 1-hour timeframe. As the name suggests, it does not simply use a normal grid (placing orders in a lattice); it automatically deforms the mechanism according to market state. The concept is simple. In range markets (no directional movement), it opens both buy and sell positions simultaneously; in trend markets (directional movement), it enters only in one direction with a trend-following approach. It automatically switches between these two modes using ADX (a momentum indicator) and EMA (smoothed moving average).

2. Features (advantages)

Deformed Grid Trade — Range: both sides; Trend: one wayIf you think of it as, on a rainy day you wear an umbrella, and on a sunny day you wear sunglasses, the idea is to use different tools (logics) depending on the market state, even for the same “market” environment. Specifically, if ADX is below a certain level, it is judged as range and both buy and sell entries are made; if it goes above, price relative to EMA is used to judge trend direction, and entries are made only in that direction. The following diagram shows this.

Figure 2: Concept diagram of deformable grid (created with Claude Design). The logic itself switches according to market state.

The design philosophy of not predicting the futureMany EAs try to predict “which direction it will move next” based on past price movement or indicators. I myself suffered from this approach in discretionary trading, so I honestly have reservations about it. Churros101B17GU adopts the opposite idea.

Instead of trying to forecast the direction before the move, it uses the reaction after the move to accumulate take-profit and stop-loss.

It is designed to earn from reactions, not predictions.

No martingale or averaging-down, manage up to 6 positionsThe method of doubling lot size to recover losses (martingale) is not used.

There is a cap on the number of positions; as the cap approaches, profits from positions with larger unrealized gains are realized, and once the cap is reached, the position with the largest unrealized loss is closed to restore balance.

This design prevents uncontrolled expansion of positions. As a note, new entry decisions are made while holding fewer than 5 positions, but the moment the range is detected, buy and sell are opened simultaneously, increasing holdings by 2 when currently at 4 positions, bringing the cap to 6.

If the market deviates from expectations, it will be stopped mechanicallyWhen buy and sell counts are imbalanced (for example, more buys by one) and move in the opposite direction by a fixed pip amount, the imbalances are corrected by individually stopping losses. It is not “enduring somehow” but mechanically cut according to predefined criteria. Automated gear adjustment according to volatility By comparing short-term and long-term ATR (a measure of price movement width), it determines whether the current market is rougher or calmer, and automatically adjusts take-profit width, distance to avoid overlapping entries, and ADX criteria continuously.

Like an automatic transmission in a car, gears are raised in rough markets and lowered in calm markets.

Magic number management to support multi-instance operationInternally, positions are managed with a “magic number” identifier, so running with other EAs or other currency pairs on the same account does not cause orders to interfere.

Portfolio operation with the Maple seriesBy combining with other EAs such as the Maple series on different currency pairs, you can have multiple revenue streams with low correlation, forming a basis for diversification. If you don’t want to put everything into one EA or one currency pair, this is worth considering.

Stability that can endure long-term unattended operationIf margin is insufficient, it automatically skips entries; if a settlement fails, it will retry up to 3 times, and decision-making occurs only when a new hourly bar is confirmed (designed to avoid reacting to every price movement).

Designed to be hard to stop even if left alone for a long time.

Long-term verification: 11 years 5 months, 2,609 tradesQuestions such as whether the parameters are tailored only to the latest market are valid.

This EA was backtested from 2015 to 2026, about 11 years and 5 months, across 2,609 trades, not relying solely on short-term optimization.

3. How we overcome drawbacks

To be honest, winning rate is high but “pain of loss” when losing is significantFirst, I’ll speak openly. The win rate is 83.33%, but the average profit is 19,672.79 while the average loss is -81,658.34, so the average loss per losing trade is about four times larger than the average profit per winning trade.

This is common for range/grid-type EAs: small, steady profits with occasional larger losses. It’s like saving up steadily and then facing a larger expense occasionally.

Simply looking at the high win rate and labeling it “safe” would be premature; please understand this asymmetry as part of the picture.

Nonetheless, a mechanism exists to limit substantial capital drawdownsTo limit losses in light of this weakness, we implement three measures: - If there is a position imbalance and the market moves against you by the expected direction, individually stop losses at a fixed pip width - If unrealized profits reach the target amount, close all positions to lock in profits - As the cap on positions approaches, take profit from the larger unrealized gains and, once the cap is reached, close the position with the largest unrealized loss to restore balance As a result, the maximum drawdown during the verification period is 10.78% of equity, and the lowest point in the period (relative drawdown) is 23.96%. It cannot be zero, but please understand that a mechanism exists to prevent infinite losses.

Addressing concerns about stopping after leaving it unattendedFull operation (24/7) raises concerns about margin shortfalls causing strange orders or failures to settle. To address this, there are three safeguards: skip entries when margin is insufficient, automatically retry settlements up to 3 times if a settlement fails, and only make decisions when a new hourly bar is confirmed.

4. Summary

Churros101B17GU centers on the idea of not trying to predict the future. For those who have suffered from prediction-driven discretionary trading or are worried about the risk of busting out via martingale or averaging-down, this design that reacts to price movement after the fact can be a viable option. If you already run other EAs and want to diversify currency pairs, consider portfolioing with other currency-pair EAs such as the Maple series. It’s about spreading risk rather than putting everything into one method or one pair. Beyond the 83.33% win rate, please also consider that average losses can exceed average profits and how we mitigated that; I would be glad if you use this as part of your decision-making. If you have questions, please feel free to ask before purchase.

Important note at the end of the trial version EA

• Automatic stop of the EA: After the term ends, all new orders, settlements, and position changes are automatically stopped (existing positions are not auto-settled).

• Handling of remaining positions: You can manually settle them, or set the same magic number to operate, so you can continue operating and settling the remaining multiple positions as they are.

  This allows you to carry over the management and settlement of remaining positions.

• Recommended actions before termination: As the period ends, please prepare to remove the EA in advance.
