How to Create an Expert Advisorfor Forex Trading
EA: Expert Advisor is a great tool for successful forex trading that trades automatically and saves the trader time and effort. This tool trades on behalf of the trader based on prearranged rules and strategies.
You can opt for an online Expert Advisor software provider like Trendonex, which has great trading strategies that make a profit. However, you can also create your own EA and set it up as per your trading requirements. So, let’s start to create your own EA.
Steps for Creating an Expert Advisor
If you are creating an EA, you must know the programming languages MQL4: MetaQoute Language 4 or MQL5: MetaQoute Language 5. These developing languages are used in Meta Trader 4 and Meta Trader 5 platforms correspondingly.
Here, we have shared the step-by-step guide for creating an EA.
1st Step: Know your Trading Strategy
First of all, you must outline the strategy of your trading to create an EA. The trading strategy must be based on a set of rules that determine when to buy and sell. The rules should be based on the trader’s risk management strategy, like stopping loss and taking profit levels. Also, consider these technical analysis indicators;
- Moving Averages
- RSI: Relative Strength Index
- Bollinger Bands and others
2nd Step: Write Code
Once you have outlined the trading strategy, the next thing you have to do is write the code. However, the code is written in MQL4 or MQL5 programming languages, depending on the software you use.
NOTE: When writing the code, remember to add the functions that let the Expert Advisor communicate with the platforms, like opening and closing the trades, setting stop loss and take profits levels, managing trade, and other customizations as per the requirement of your trading.
3rd Step: Test the EA: Expert Advisor
After writing the code on the platform, now test the EA using the historical data or via forward testing. This procedure confirms that the EA works as expected and is profitable.
However, the testing via historical data involves running the EA on past data to check how it would have been executed in the past. You can use the backtesting function from Meta Trader software to perform historical testing. Furthermore, forward testing involves running the EA on live data to check how it works in real-time. Forward testing procedure is more consistent than historical testing as it uses up-to-date market circumstances.
4th Step: Adjust the EA As Per your Trading Strategy
Once you have checked the EA that you create next, you have to set it up via the available feature of Meta Trader. The setting of EA involves adjusting the trading rules and risk management rules to progress EA’s performance. Moreover, the adjustment and optimizing procedure also involve testing the EA with different parameter values to check which value makes the best results.
NOTE: Keep in mind that do not over-optimize the Expert Advisor, as it can lead to curve fitting. In this situation, EA is optimized for previous data and performs unwell at the current time.
5th Step: Organize the EA
Once you have adjusted the EA as per your trading strategy, then you have to organize it. Use a VPS: virtual private server to make sure that it trades and works 24/7. While VPS function also makes sure that the EA is always connected to the internet and that it does not miss any trading opportunities.
Tips to Remember Before Launching Your Expert Advisor
So, you have just created your own Forex EA and are ready to launch it. Here, we have described some tips to make it work properly.
Debugging
Writing an Expert Advisor code in the Meta trader platform is so difficult if there is a debug in the code. The policy of MetaQoute doesn’t have a debugger tool. To sort out this issue, input the print function directly into the code, which is very hard to manage. Moreover, you can also download the online DebugView software to check methodologically formatted logs.
Backtesting Data
Probably, you are thinking that great backtesting results are proof of your program being ready to prosper; thus, unfortunately, it is not that simple. The results basically depend on the quality of the data applied in the backtesting procedure.
So, if you put the poor data it can lead to defective consequences. The default data in MetaTrader 4 and MetaTrader 5 can only grasp a modeling worth of up to 90 percent. It can cause significant differences in backtesting and the live experience, mainly in minor time frames.
Check MetaTrader Connection
Make sure the MetaTrader connection is turned on and connected directly to your broker to run your expert Advisor. However, the MetaTrader platform is designed to robotically reconnect to the server without any issue while it does not always perform as expected.
So, if you have multiple MetaTrader accounts, the incorrect credentials are used in the connection. To sort it out, delete your unapplied accounts in the Meta Trader.
Execution Speed
Mt4 and MT5 perform on a trading session length of half a minute or 30 seconds. If you are using a Forex EA, your session will time out automatically if there is no trading activity for more than 30 seconds. Getting into the trading session requires an IP address with a password and login.
However, it can take some time, even up to two seconds with some traders. Delays can have a considerable influence on the outcome of your trades.
