Teach how to code a gold trading program using BB + RSI

\r\n

Hi everyone, in this article, I will guide everyone through the process of coding an Expert Advisor from scratch.

\r\n

Before getting into the content, let me first thank our sponsors for our articles.

\r\n

\r\n

Here we go!

\r\n

1. Make a trading plan

\r\n

$\"\"$

\r\n

In the process of trading planning, it is not necessary to come up with everything on your own. In today's world, there are many sources of information and experienced traders who offer both free and paid trading education.

\r\n

Our responsibility is to invest our own efforts and time to learn and develop our trading plans based on the knowledge and insights we acquire.

\r\n

2. Always ask questions beforehand

\r\n

$\"\"$

\r\n

When starting a design or planning process, I want everyone to ask questions.

\r\n

The first obvious question would be, \"Which technique to use?\"

\r\n

To answer that, backtesting is crucial. Only through backtesting can we determine which techniques work best.

\r\n

The subsequent questions could be about the capital required, which currency pairs to trade, and which timeframe to use.

\r\n

Feel free to come up with many questions.

\r\n

Sometimes, questions may seem silly or without substance, but you never know.

\r\n

Those questions might spark our imagination and lead us to discover new paths or secret formulas.

\r\n

3. Today's trading technique

\r\n

$\"\"$

\r\n

If you have found an interesting trading technique that someone else has shared, and you want to use it to code a trading bot program today, that's perfectly fine. You can use an EA to backtest the technique as it provides faster and more accurate results compared to manually taking notes and analyzing the data.

\r\n

4. Flowchart

\r\n

$\"\"$

\r\n

Writing a detailed flowchart is indeed beneficial. The more detailed the flowchart, the easier it becomes to convert it into code.

\r\n

In the beginning, I recommend practicing writing flowcharts frequently. As we continue to write them, we become more familiar with the process.

\r\n

After some time, large flowcharts of new programs start to form in our minds naturally, allowing us to start programming without necessarily having to write a flowchart first. It's like the flowchart floats into our thoughts. That's when we can start writing the program right away, without relying on the physical flowchart. LOL

\r\n

Flowchart Example

\r\n

$\"\"$

\r\n

The example above shows a simple arrow diagram. Notice how the arrows indicate what action to take after completing each step.

\r\n

This is crucial because if we don't know what needs to be done before and after each step, programming can become confusing and disorganized.

\r\n

$\"\"$

\r\n

Once we have established the sequence of operations, let's take a look at a code example.

\r\n

You will see that if we have planned properly, the remaining task becomes much easier, which is refining and improving the code continuously.

\r\n

5. Coding

\r\n

\r\n

6. Modify and customize the EA

\r\n

$\"\"$

\r\n

In this topic, let's continue to ask additional questions together.

\r\n

Because every time after we finish coding a program for the first time, we are bound to encounter challenges.

\r\n

Or perhaps we may come across new and interesting ideas or concepts to explore further.

\r\n

Frequently asked questions I always ask myself. If I increase the range of the stop-loss, will it result in higher profitability?

\r\n

It may sound counterintuitive, but increase the range of the stop-loss actually help minimize losses and improve overall profitability.

\r\n

Yes, indeed! That's right. It may result in higher losses, but for me personally, if it leads to higher profits, I would do it.

\r\n

This is a point where everyone may have different thoughts. Therefore, I encourage you to ask yourself the question and determine what works best for you.

\r\n

Let's start coding the program together!

\r\n

First of all, I would like everyone to access their own MT4 program.

\r\n

I recommend downloading it from TMGM because not only do they sponsor us, but their platform also offers a wide range of historical data on charts. LOL

\r\n

$\"\"$

\r\n

Once you are in MT4, press the F4 button to access the MQL4 program.

\r\n

Click the \"New\" button on the top left to create a new Code file.

\r\n

$\"\"$

\r\n

$\"\"$

\r\n

In the \"Name\" field, you can set any name you prefer, but please don't remove \"Experts/\".

\r\n

For the \"Author\" field, enter your own name.

\r\n

If you have a website, you can include the link.

\r\n

Then, click \"Next\" repeatedly to proceed and you will have the file as shown in the image.

\r\n

The main function we will use is \"OnTick()\". It is used to instruct the program to perform actions when the chart moves.

\r\n

Here is a code

\r\n

The first part is about the input we want to use. I recommend placing them at the top or near the function we are currently writing in the code.

\r\n

I've included 3 input parameters that I entered because I assumed that adjusting these 3 values would improve the EA's performance. This way, we won't have to make changes directly in the code.

\r\n

Furthermore, we can use MT4 to find the optimal values through optimization.

\r\n

In addition to that, I have also created two sets of variables for the Bollinger Bands.

\r\n

The first set of variables is used to set the take profit (TP) and stop loss (SL) levels.

\r\n

The second set of variables is used to identify entry signals in conjunction with the RSI indicator.

\r\n

In this case, I have implemented the code for entering only a BUY order.

\r\n

If anyone is interested in further developing their skills, I encourage you to take the code and add the logic for entering a SELL order as well. Then, please come back and share your review and feedback.

\r\n

input double lot = 0.01;//Lot size (max: 80 lots)

\r\n

input int stoplossPoint = 500;//Stop loss point above or below BB

\r\n

input int rsiPeriod = 20;//RSI period

\r\n

int openBar = Bars - 1;//keep last open bar

\r\n

void OnTick() {

\r\n

double bbu_n = iBands(Symbol(), PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_UPPER, 0);

\r\n

double bbm_n = iBands(Symbol(), PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_MAIN, 0);

\r\n

double bbl_n = iBands(Symbol(), PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 0);

\r\n

double bbu = iBands(Symbol(), PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_UPPER, 1);

\r\n

double bbm = iBands(Symbol(), PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_MAIN, 1);

\r\n

double bbl = iBands(Symbol(), PERIOD_CURRENT, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 1);

\r\n

double rsi = iRSI(Symbol(), PERIOD_CURRENT, 14, PRICE_CLOSE, 1);

\r\n

if(

\r\n

(Close[1] < bbl) //con1

\r\n

&& (rsi < rsiPeriod)//con2

\r\n

&& (openBar < Bars)

\r\n

) {

\r\n

double price = Ask;

\r\n

double stoploss = NormalizeDouble(bbl_n - (stoplossPoint * Point), Digits);

\r\n

double takeprofit = NormalizeDouble(bbm_n, Digits);

\r\n

int ticket = OrderSend(Symbol(), OP_BUY, lot, price, 3, stoploss, takeprofit, \"BBLOW\", 16384, 0, clrGreen);

\r\n

openBar = Bars;

\r\n

}

}
