"Spread Auditor Pro v1.00"
〜 Visualize the maximum spreads, liquidity, and price ranges over 24 hours with data to fully unlock the true potential of your EA 〜
Hello! To all traders and EA developers, thank you for your daily trading efforts.
Have you ever thought while operating an EA (expert advisor) like this?
- “I want to minimize trading costs (spreads) and increase the net profit I keep on hand.”
- “I want to avoid unnecessary spread widening late at night or early morning, to enter safer and more favorable positions.”
- “I want to understand the true spread tendency of my account and optimize the operating times of my EA.”
No matter how excellent an EA’s logic is,if you operate without understanding broker trading costs (dynamic spread changes), you may erode the profits you could have earnedover time.
Many FX companies publish figures like “average spread 0.8 pips ~,” but those are data centered on busy daytime trading.
What we truly need to know is,“How does the spread widen over 24 hours, and which times are most stable?”— objective, real-world measured data.
Therefore, we have developed a high-precision spread auditing EA, 『Spread Auditor Pro v1.00』, to correctly understand your favorite account’s trading environment and to extract 100% of EA performance!
In this article, we will present the tool’s main body (.ex5) and the official user manual PDFcompletely freeas a gift.
1. The immense benefits of “grasping the spread environment with data”
Every FX broker account has its own strengths based on market liquidity—the “preferred time window” and the “times when spreads widen more easily,” which are their own quirks.
Such as unemployment reports or FOMC; spreads widen momentarily due to order clustering across any broker (natural market phenomena at data releases).
Around 5:30–7:30 JST. As New York closes and the date updates, liquidity decreases and spreads widen.
The most valuable aspect here is,the stability of spreads during normal timesandthe exact time when the early-morning widening converges back to normalwith precise numbers.
- “This account returns to normal spreads by 6:40 AM, so we can enter without missing the morning opportunities.”
- “This account tends to widen spreads until around 7:20 AM, so set EA operating time from 7:30 to reduce costs.”
By fine-tuning operating schedules and spread filters to match an account’s actual conditions, you can minimize unnecessary costs and maximize net profits on hand!
2. Five standout features of the ultra-light Spread Auditor Pro
With the philosophy of “because it runs 24 hours, it must be extremely lightweight,” we distilled the tool to only the essential measurement features in their simplest form.
This allows detailed analysis of whether widening occurred due to rapid price movement or due to low liquidity.
【Only one day of measurement】If you set parameter to “24 hours,” after a full day of records, safely save the CSV and automatically exit from the chart (auto unload).
3. Contents of the generated CSV data
In MT5'sMQL5/Files/folder, a clean 5-column CSV is recorded every minute as follows.
| Column | Item | Recorded content and usage |
|---|---|---|
| Time | Record time | Minute timestamp in the format YYYY.MM.DD HH:MM |
| MaxSpread_Pips | Maximum spread | Worst value for that minute. Use to determine cost trends by time of day |
| TickCount | Total ticks | Number of price updates. Visualizes market liquidity (activity) |
| PriceRange_Pips | Price range | Difference between high and low in that minute. Assess market volatility |
| WideTicks | Duration above widening threshold | Count of times it exceeded the set value (e.g., 2.0 pips). Assesses continuity of spread widening |
4. Recommended use: Create optimization reports for your account with AI (ChatGPT / Gemini)!
CSV data collected can be visually understood simply by plotting line graphs in Excel, butuploading the CSV to AI (ChatGPT, Claude, Gemini) as-is to obtain optimization suggestions is incredibly convenient!
① List of average maximum spreads by time slot (0:00–23:00).
② Analysis of widening times during early morning rollovers (start to normal return time).
③ Recommended operating time filter settings for maximizing EA profits on this account.
Please summarize into a report.”
- “After 7:00 JST, spreads quickly return to normal (about 1.0 pips) and trading environment is very stable.”
- “Between 6:00–6:45 JST, spread widening tends to continue, so starting EA operation after 7:00 can greatly reduce trading costs.”
- “Core market hours for Europe and the Americas (16:00–24:00) have abundant ticks and very tight spreads, making them most suitable for day trading and scalping.”
