OMS Frequently Asked Questions

OMS works in conjunction with the MetaTrader Strategy Tester to help algo traders produce more profitable trading strategies.

We let MetaTrader do what it does really well: perform the 'mechanical' function of running the optimizations and backtests.

OMS then helps the trader with deep analysis of the results, incorporating proven best-practice, to help the trader make more informed decisions, that are much more likely to result in profitable robust strategies when operating in live accounts.

By combining the strengths of MetaTrader and OMS, the result is something more valuable than the sum of the parts. You will have a professional-grade backtesting and optimization suite at your fingertips, allowing you to rigorously find the patterns in your data to help create more profitable, more resilient Expert Advisors.

OMS utilizes standard interfaces that are fully supported and documented by MetaQuotes.

Yes, absolutely. Your expert advisor is your private intellectual property. We don't ask you to upload your EA to our servers like some backtesting services do. We believe that the IP you've worked so hard to develop, should stay 'your' intellectual property.

Yes, any combination of core types can be used simultaneously to undertake an optimization.

Note however, that when using the MQL5 Cloud Network, you will need an account with MetaQuaotes, and you are fully responsible for any costs to use their cloud platform.

Yes, genetic optimizations are fully supported.

Note however, that by the very nature of genetic optimizations, some parts of the n-dimensional parameter space might not have many values. OMS handles this but the user should be aware that this can affect statistical significance in the more sparse areas. This is the trade-off between fast optimizations and statistical significance, regardless of whether OMS is being used or not.

No (not yet). We would consider porting to other platforms if there was sufficient demand. If you use another platform and think that OMS would add value to the backtesting and optimization capabilities of that platform, please contact us with details.

In the initial realease, only MT5 is supported however, MT4 support is planned for February 2026.

Yes, we have a customer-only Discord group. You will be invited following your purchase, but joining is of course optional.

Yes absolutely! We really encourage this. Enter details of your request in the feature-request forum on the Discord group. Please provide as much detail as possible about the new feature/functionality, and justify the reasoning behind why you think this would benefit OMS customers.

We can't guarantee we'll implement every request (for example, if it isn't aligned with our longer-term roadmap), but if we agree it would be beneficial to the majority of users, we'll do our best to ensure it is incorporated into a future release.

Unfortunately not. The two products use different (and conflicting) methodologies to optimize parameters. Walk Forward Pro focusses on adapting parameters as market conditions change, but can suffer with statistical significance, especially with strategies that don't have sufficient sample size (number of uncorrelated trades).

OMS on the other hand, manages statistical significance much more effectively by focussing on just single in-sample and single out-of-sample epochs, meaning results have a higher statistical significance and will help produce strategies that are much more robust (but with the downside that parameters are not automatically adapted as market conditions change over time, but additional optimizations can resolve this when using OMS).

Significant effort has been taken to ensure Opt My Strategy's code is optimized as much as possible, to reduce any performance degradation. Over a 10 year backtest, you can expect the duration to increase by approximately 1 or 2 seconds. On our Test PC this 10 year backtest benchmark increased the test time by less than 1s.

Our affiliate programme is one of the most generous you'll find. All affiliates will be provided with an 'Affiliate ID'. You can then share links (that include your ID) on your website, social media, in video descriptions, or directly with your community of traders, helping make other traders aware of Opt My Strategy. If anyone follows your link and then continues to purchase OMS, we will share a generous percentage of the price paid with you. See more details here

Yes. Simply cancel with our thrid-party payment provider (you'll receive an email following subscription with a link). We do not offer refunds if you cancel mid-subscription period but you can continue using the software until the end of that period.

Yes, if you are a subscriber, you will receive support and updates for as long as you maintain your subscription.

No. Subscriptions are for 1 device only. If you want to change devices in the future as you upgrade your PC, switching is of course allowed, providing OMS is removed from the previous device. However, our servers are configured to detect use from multiple installations, so please do not share your User ID with anyone else. This could result in your license being deactivated without refund.

You can only do this if you both share the same PC. When you buy a subscription it should only be installed onto a single PC at a time (you can switch your license over to new PCs as you upgrade your hardware in the future, but we do not allow continual switching).

No, you are not committed to any further costs. One-time purchase licenses come with support and software updates the first 12 months. However, after that time, if you wish to continue receiving support and new version updates, you have the option of purchasing an additional 12 month's of support and updates. It is completely optional to do this and you can buy additional years intermittently if you wish (e.g. every 2 or 3 years) to bring your version up to date. For the cost if this 12-month package see our pricing page

One-time purchase licenses come with software version updates the first 12 months. However, at any time after this initial period has ended, you have the option of purchasing an additional 12 month's of support and updates, to bring your version right back up to date, and to keep things simple we do not force you to pay for any gaps inbetween. The price of this 12-month package can be found on our pricing page

OMS licenses are 'device-based'. So you can only share with a colleague/friend if you both share the same PC. When you buy a lifetime license it can only be installed onto 1 device. Our servers are configured to detect multi-device use, so please don't. We could disable your account without refund if we detect that you have shared your OMS User ID

No, the Corporate Subscription is designed for comapny use by multiple employees. You might however be interested in joining our OMS Affiliate Programme which allows you to benefit financially from OMS sales.

Yes, absolutely. Your expert advisor is your private intellectual property. We don't ask you to upload your EA to our servers like some backtesting services do. We believe that the intellectual property you've worked so hard to develop, should stay 'yours'.

Firstly, OMS works in conjunction with the MetaTrader Strategy Tester. Therefore your EA will only work with OMS if it already runs correctly and produces results in the standard MT4 or MT5 Strategy Testers. If it doesn't then you will not be able to use OMS either.

Secondly, there are a few minor code snippet additions you'll need to make to the code of your EA (don't worry we provide the code and tell you where to place it). But this does mean you must have edit access to the .mq4 or .mq5 source files. If you have purchased an EA and only have the compiled .ex4 or .ex5 files, you will not be able to use it with OMS.

Other than this, yes, OMS should work with your EA just fine.

No.OMS is not a silver bullet that can turn an illogical system without an edge, into a profitable system. You still need to be prepared to put in the hard work to build a trading system that has a viable edge in the market and has a chance of being traded successfully.

What OMS will do is allow you to sqeeze every last drop of value from your EA, in addition to helping ensure it is robust. If OMS identifies that the EA has little chance of being profitable, this will be evident in the OMS charts - this could potentially save you a lot of money!

No there isn't, but experience has shown us that the more parameters you simultaneously optimize (the number of degrees of freedom), the more likely is is that your strategy will be over-optimized/curve fitted. Therefore, in addition to using OMS, it is also necessary to be sensible about the number of parameters that you optimize in order to produce a robust strategy.

Yes. We fully support the use of your own custom performance criterium, but also provide our own if you don't.

OMS licenses are device-based, so for the majority of license types this means one device. We also provide Corporate subscriptions that allow installation on 10 devices within an organisation.

As you upgrade your hardware in the future, we of course allow you to transfer your license to a new PC, but you should uninstall it from your previous PC.

The vast majority of users have no problems at all. If you have written or modified mql4 / mql5 code before then you should find the process very simple and straight forward. If this is not the case then we will assist you in making the changes if you wish us to. Remember that you will need access to the .mq4 / .mq5 source code in order to make the changes. If you have bought an EA and only have access to the compiled .ex4 / .ex5 files, then you will not be able to use OMS.
