Expert Advisor (EA) for MT4 and MT5
An EA is a bot that runs inside MetaTrader. It is the most common forex bot. We write clean MQL4 and MQL5 code and test it on your broker's real conditions.
The forex market runs 24 hours a day, five days a week. No trader can watch it all the time. A forex trading bot fixes this. It follows your rules, scans the charts, and places trades in milliseconds.
Core Devs is a trusted forex trading bot development company in Dubai. We build custom bots for traders, prop firm traders, signal providers, and brokers. We started in 2020 and have delivered 100+ projects since then. Our team writes Expert Advisors for MT4 and MT5, cBots for cTrader, and custom bots that connect to broker APIs.
A forex trading bot is software that trades currency pairs for you. People also call it a forex robot, a forex EA, or an automated forex trading system. It connects to your broker account, reads live prices, checks your rules, and sends orders when the rules match.
You set the strategy. The bot does the watching and the clicking. It does not get tired, and it does not trade out of fear or greed.
How forex bot trading works
Many people use forex bots. These are the most common groups we work with.
If you fit one of these groups, a custom bot can save you hours every week.
We build every bot around your strategy. These are the types our clients ask for most.
An EA is a bot that runs inside MetaTrader. It is the most common forex bot. We write clean MQL4 and MQL5 code and test it on your broker's real conditions.
A cBot runs inside cTrader and uses C#. It suits traders who like cTrader's fast execution and clear charts.
This bot reads moving averages, breakouts, and momentum. It enters when a trend starts and exits when the trend fades.
This bot makes many small trades in a short time. It needs low spreads and fast execution, so we build and test it with both in mind.
This bot opens orders at set price steps or opens opposite positions to limit loss. We add strict limits so the risk stays under control.
This bot reacts to economic releases like interest rate decisions and jobs data. It can also pause trading before big news. Many traders use this filter to avoid wild price spikes.
Prop firms have strict rules on daily loss, total drawdown, and trading style. We build bots that follow these rules and stop trading before you break them.
This bot copies trades from a lead account to other accounts, or sends signals to Telegram. Signal providers and trading communities use it often.
You have an indicator or a TradingView script you like. We turn it into a bot that trades on its own.

| Point | Forex Bot | Manual Trading |
|---|---|---|
| Screen time | Runs 24/5 on its own | You must watch the charts |
| Speed | Places orders in milliseconds | Depends on your reaction |
| Emotion | Follows the rules every time | Fear and greed can change your plan |
| Testing | You can backtest on past data | Hard to test fully |
| Risk | Needs strong limits and checks | Needs strong discipline |
A bot does not replace your strategy. It runs your strategy with more speed and more discipline.
Many bots fail for simple reasons. We plan for them from day one.
A bot can look perfect on past data and fail live.
We test on separate data sets and on a demo account to catch this.
These costs can kill a scalping bot.
We test with real broker conditions.
One bad day can wipe an account.
We add hard limits that stop the bot.
Brokers differ in execution, symbols, and rules.
We tune your bot for your broker.
A trading bot touches your money, so security comes first.
We learn your strategy, your broker, and your goals.
We pick the right platform (MT4, MT5, cTrader, or custom) and draw a clear roadmap.
We build in stages and share progress often.
We test on past data and then on a demo account with live prices.
We set up the bot on your account or VPS and watch the first live trades with you.
We monitor the bot, fix issues, and improve it as markets change.
We help you pick the right platform.
Dubai has strict financial rules. The SCA and the DFSA oversee brokers and financial firms in the UAE. We build the software. You or your broker must hold the right license to offer the service to others.
If you plan to run a bot for clients, consult a legal expert first. We can build the technical side to support your compliance needs, such as trade logs and reports.
Not every developer understands trading. Ask these questions before you hire a team.
A good team understands spreads, slippage, lot sizes, and margin.
Ask how they backtest and how they avoid overfitting.
Stop-loss, daily loss limits, and a kill switch should come as standard.
You should get the full source code and clear rights to use it.
Brokers change rules, and markets change. Your bot needs updates.
You should get honest answers, a clear price, and a clear timeline.
At Core Devs, we answer yes to all six. We also tell you early if your idea needs a change.
The cost depends on your scope. Pricing varies depending on key factors such as the trading strategy, platform, total currency pairs, and dashboard requirements.
