How it works
From trading idea to working EA in four steps
- 01
Share your strategy
Send us your rules: entries, exits, stop loss, position sizing and filters. Marked-up charts and notes help.
- 02
Agree the specification
We write your rules up as a clear specification and send a quote before any work starts.
- 03
Build and test
We code the EA for MT4 or MT5, check in the Strategy Tester that it trades exactly as specified, then run it on a demo account.
- 04
Delivery and support
You receive the EA, its settings and a short guide, and run it on your own terminal or VPS.
Strategy automation
Your rules, executed exactly
An Expert Advisor never hesitates, skips a trade or moves a stop out of fear. It does exactly what your rules say, on every tick and in every session.
We build in the risk controls you want, so every trade has a defined plan before it opens.
- Entries, stop losses and multiple targets, as you define them
- Position size from a fixed lot or a % of your balance
- Session, spread and news filters
- Break-even, trailing stops and partial closes

Why ForexBob
EAs built by a trader, for every session
The forex market trades 24 hours a day, five days a week, from Sydney to New York. An EA has to behave correctly in all of it: the quiet hours, the opens and the news.
Sydney session · 22:00 – 07:00 GMT
SydneyTokyoLondonNew York
Session times are approximate, in GMT, and shift with daylight saving.
Built by a trader
Run by Sukhwinder Singh, a trader and Expert Advisor developer with more than 10 years in the markets.
Specification first
Every project starts with your rules in writing, so the EA does what you expect and nothing else.
Risk controls built in
Stop losses, position sizing, spread and session filters are part of every build, not extras.
Tested before delivery
Every EA is checked in the Strategy Tester and on a demo account, and we explain what the results can and can't tell you.
Broker time handled
Server time zones and daylight saving changes are handled in code, a common source of silent EA errors.
Support after delivery

FAQ
Questions about Expert Advisors
What is an Expert Advisor?
An Expert Advisor (EA) is a program that runs inside MetaTrader 4 or 5 and opens, manages and closes trades by itself, following fixed rules. It watches the market around the clock, applies your stop loss and position sizing on every trade, and never skips a setup or hesitates. More on how EAs work.
How does custom EA development work?
You send us your trading rules: entries, exits, stop loss, position sizing and filters. We write them up as a specification and send a quote before any work starts. Then we code the EA, check in the Strategy Tester that it trades exactly as specified, run it on a demo account and deliver it with a short guide.
How much does a custom EA cost?
It depends on how complex the strategy is. A single entry signal with a fixed stop and target is a small job, while multi-timeframe filters, several open positions or a trade panel take longer. You get a quote and an estimated timeline with the specification, before any work starts.
Should I choose MT4 or MT5?
Choose the platform your broker supports and you already trade on. MetaTrader 5 is the newer one, with more timeframes and a faster strategy tester that can test on real tick data, and most brokers offer it. MetaTrader 4 is still widely used for forex. We build for both. See MT4 vs MT5.
Can you guarantee an EA will be profitable?
No, and nobody honest can. An EA follows its rules exactly, but markets change, and a backtest only shows how the rules would have traded in the past. We test that the EA does what was specified and tell you if we see warning signs such as curve fitting. Trading forex carries a high level of risk.
Is my strategy kept private?
Yes. Your strategy stays yours. We don't share it or reuse it in our own AETHON EAs, and you run the finished EA on your own MetaTrader terminal or VPS. We never ask for access to your trading account or your login details.
