How to Create your First Expert Advisor (EA)
In the following example, the Expert Advisor we are going to build is based on an SMA crossover.
-Go to Expert Advisor Builder’s website, and sign-up (it takes a couple of minutes)
→ After, go to a new MetaTrader 4 Strategy, open a new strategy, and name it MA Cross.
→ Now you must add your condition. Go to Add condition.
There are three available fields (LEFT, MIDDLE, RIGHT):
Insert Moving Average 5 periods on the LEFT field, on the MIDDLE choose crosses above, on the RIGHT insert Moving Average 20 periods.

Note: There is a significant difference between 'is above' and 'crosses above'.
- 'Is above' creates a continuous signal and that means that you will open order for every tick, as long as the moving average with period 5 is above the moving average with period 20
- Crosses above create a unique signal and that means only a single order once at the crossover
→ After you have selected the right condition, click OK.
Creating a Selling Order
Tip: Click the magic button to create the opposite conditions for a selling order.
→ Now do the exact opposite in order to close the trade. Create the exact opposite order to close short positions. In the Common tab, you can find additional options.
In order to perform the right Money Management, insert the lot size. Note that 1 standard lot is 100,000 USD, therefore, if you want to trade smaller positions insert the right lot size (0.5, 0.1, 0.05, etc.).
→ Now you can add also some alerts, for example, you can check Audible Alerts in order to hear a sound every time an order is executed.
That is all, the first Expert Advisor is ready as the source code is generated. You can copy the source code and compile it on MT4.
Backtesting your First Expert Advisor
MT4 offers a very useful tool for performing historical backtesting.
→ Go to MT4, then Go to View -> Strategy Tester.
→ Choose the Expert Advisor you have just created and test it (you may need to restart MT4).
→ Select any currency symbol, the time frame, and start the MT4 tester.
Avoiding Multiple Crossovers
As the price fluctuates, the MAs may cross upwards and downwards multiple times inside a single bar. There is a solution for that, check the option Next Open Trade After (Common tab)
select for example 5 bars, and, Minimum Trade Duration also 5 bars
Now your Expert Advisor will wait for 5 bars before opening the next trade or before closing the open position.
Creating Inputs for your Expert Advisors
The first input is the time when pending orders are placed.
→ Go to your strategy and edit conditions...
→ Go to checkbox titled "Add to inputs".
→ And add the new input...
→ Add any name...
→ Now the condition appears in the list of inputs.
→ You can add additional time conditions. The next condition will be the optimization of the Take Profit order (in Pips).

Add the new condition again to inputs. Adding the New Input...
And now replace the suggested name. Now Click OK three times.
The Take Profit value has been replaced by a variable name.
Optimizing the Trailing Stop Order
The number of bars determines how often the Stop Loss is moved. Add to inputs...
Add the new input...
Now copy the source, replace the old source and compile it on MT4.
As the Expert Advisor Builder team suggest, you can also experiment using the Average True Range indicator instead of the number of pips.
