Forex EA (Expert Advisor) specifically refers to automated trading systems that run on MT4/5 terminals. EA can automatically monitor the market and execute orders 24 hours a day, effectively avoiding the impact of time, physical strength, emotions and other factors on manual trading. For more details, please see the Appendix at the end of the article.
Almost every Commercial EA vendor will provide the corresponding backtest data. One should download or request a Demo Version to fully assess whether the data can be duplicated.
This is one of the most popular MT4 EAs in a third party Forex EA sales sites. Not only is it ranked on the front page, but all users give 5-star reviews. The vendor said the EA was designed with advanced algorithms and utilized deep learning technology, providing the MT5 Tickdata backtest report, the yield curve of EURUSD, AUDUSD, GBPUSD was a straight linear rise. (Tickdata is the abbreviation of Tick-by-tick data. It's a type of financial market data that records every individual transaction that occurs for a particular financial instrument, such as a stock, commodity, or currency pair. For currency pairs, the Tickdata currently available is based on M1 Timeframe.)
About the EA
Backtest of EUR/USD provided by the vendor
After downloading the demo version, we ran a Tiackdata Backtest on EURUSD in MT4, and the yield curve was basically the same as the vendor provided. (Default Setting, Spread= Fixed 1 pip, No Slippage)
Tickdata backtest from 2010
The price of this EA is $938, which is slightly higher than the other EAs on the site, but it is certainly a Holy Grail to have such a consistently profitable EA. Backtesting results show that an initial investment of $10k generated $130 Million after 13 years in EURUSD. The initial one-time $938 investment seems very cheap.
However, after the mood calmed down a bit, a new question arose: With such a stable and profitable EA, why would the vendor sell it at such a low price of $938 instead of trading it himself? In addition, in the spirit of being highly responsible for our own money, we tried to modify the timing of Tickdata and re-tested it with the exact same quote.
A miracle did occur at this time, and we saw that the results of all backtests were basically a steady decline in a straight line.
Tickdata backtest from 1975
Tickdata backtest from 1982
Comparing the backtest results before and after modifying the timing of the data, we have to think that this is a potential Scam EA.
Conclusion
1. Before purchasing any Commercial EA, be sure to run a Tickdata backtest.
2. It is necessary to modify the timing of the Tickdata for the testing.
3. Even if the results are satisfactory, it is necessary to think differently: From the author's point of view and psychology, assume you have created a stable and profitable EA through years of study and practice, why don't you make money by trading yourself, but sell this EA? Especially most No DLL EAs can be decompiled very easily within a few minutes. Then think about the various potential problems from that perspective.

Appendix
Forex EA (Expert Advisor) specifically refers to automated trading systems that run on MT4/5 terminals. In general, EA is based on proven manual trading methods and experience, built with various technical indicators and coded in MQL language. EA can automatically monitor the market and execute orders 24 hours a day, effectively avoiding the impact of time, physical strength, emotions and other factors on manual trading. EA is one of the most important trading tools for both professional and retail traders.
In addition, through rigorous and scientific backtesting, we can not only test whether the key logic of the EA is feasible, but also have a reasonable expectation of the risk and reward of trading performance in the future.
However, MT4/5 EA is not omnipotent. The MQL language is similar to the C language, the function is relatively simple. Some complex and/or advanced trading logic can not be expressed well. Then we need to use Java Script and other languages in eSignal, Reuters Eikon, CQG or other professional platforms to build the trading system.
The series of articles "Commercial EA Review by LinoCapital" aims to provide readers with some principled guidance in selecting a commercial EA through our knowledge and experience. Welcome to all kinds of feedback and discussion.
We hope all the traders succeed. Good Luck!

EUR/USD faces extra pressure, drops below 1.1800
EUR/USD trades on the defensive, slipping back below the 1.1800 support on Thursday, all in response to decent gains in the US Dollar. Earlier on Thursday, the ECB matched consensus and left its policy rates unchanged, while President Largarde delivered quite a neutral press conference.
GBP/USD falls to new lows near 1.3530
GBP/USD extends Wednesday’s pullback on Thursday, easing lower towards two week lows around the 1.3530 area. Ongoing strength in the Greenback and the dovish hold from the BoE at its earlier meeting are keeping demand for the British Pound on the defensive for now.
Japanese Yen hangs near two-week low vs. firmer USD; USD/JPY bulls target 157.00 breakout
The Japanese Yen extends its sideways consolidative price move against a broadly firmer US Dollar and currently trades near a two-week low, touched earlier this Thursday. Investors remain worried about Japan's financial health on the back of Prime Minister Sanae Takaichi's expansionary fiscal plans. This, along with political uncertainty ahead of the snap election on February 8, has been another bearish development for the JPY and contributes to its relative underperformance.

Gold fails to sustain gains above $5,000 for third consecutive day
Gold is back under pressure on Thursday, slipping back towards the $4,800 region per troy ounce. A firmer US Dollar is weighing on the yellow metal, even as the broader mood remains risk off. That said, falling US Treasury yields across the curve are helping to cushion the downside and, for now at least, are limiting the depth of the pullback.
Strategy's Bitcoin treasury in focus as MSTR crashes alongside crypto market
Strategy (MSTR), the largest corporate holder of Bitcoin (BTC), is in focus ahead of its earnings call on Thursday amid an intensifying crypto market sell-off. Also caught in the headwinds is the MSTR stock, trading at $114 at the time of writing, down over 12% intraday.
The AI mirror just turned on tech and nobody likes the reflection
Tech just got hit with a different kind of selloff. Not the usual rates tantrum, not a recession whisper, not even an earnings miss in the classic sense. This was the market staring into an AI mirror and recoiling at its reflection.
