Hi D.s, was thinking create own system. It actually should be very useful, because don't want to sit in front of computer all day staring to monitor and trading anymore but the system can't go around release fresh news. Thinking that it could don't trade before few hours and after few hours release news but if already in the market some trade it should dynamically recognise don't trade and even after news or something like that, like finger print or what so ever without SL. Maybe, it is already some engine that special create for news trading or...
Sorry bro. I don't have any news related trading system. I personally prefer to stay out of news as there is no logic to the price movement during big news events.

Agree with you per news its better stay away from the market. Thank you anyway. Maybe, have any ideas how to code that ea for example take notice lets say from forexfactory.com about news and stop trading or shout down trading session and after awhile, again start to trade after 1hours? Im guessing that to recognise unplanned news its sounds like depends on high momentum. Your thoughts?

reading data from a different website other than your broker server is difficult to code using MT4. I still have never tried to read anything from any particular website. to read from web page, you need a good quality parser to recognize required information from the web page. The website owner will never allow you to directly access their servers database to read the data unless you are in a partnership with that website and doing business together.

So clearly speaking, Its not possible. May b you can manually go to the website daily and copy the required data and store it in a text file and your EA will read from it whole day and work accordingly and then next day you need to again replace the text file content for that day.

yes it is possible. I don't have it with me. But its easy to create it. So try creating it.


For example in my code template file you can find this code

void Breakeven()
{
total = OrdersTotal();
double ns=0;
for( i=total-1;i>=0;i--)
{
if(!OrderSelect(i, SELECT_BY_POS)) continue;
if(OrderMagicNumber() != Magic || OrderSymbol() != Symbol()) continue;
if(OrderType() == OP_BUY)
ns = PipsAdd(OrderOpenPrice(),Spread,1);
else if(OrderType() == OP_SELL)
ns = PipsAdd(OrderOpenPrice(),Spread,2);
if(OrderStopLoss() !=ns && !OrderModify(OrderTicket(),OrderOpenPrice(),ns,OrderTakeProfit(),0,Blue))
{
printf("error modifying stop loss"+ ns);
break;
}
}
}

In this code "ns" is the price where the trade has originated. As this is for break even. So the stoploss is modified to "ns" price when this function is called.
If u need to add more for profit just add it to "ns" , so that stoploss will be moved to more profitable place. just make sure price has crossed that point else you will get the mentioned error message.

Marshalmax .. i can only send one mail per 24 hour. So this is the reply

What i understood that, the stoploss is taking more pips then you originally intent it to take( box range + spread ). If i am wrong just correct me.
Assuming what i understood is correct then you want to put your stoploss without the spread amount. This calculation cannot be directly done using Ea builder. You need to modify the code manually.
Just before the open trade function is used, you need to find the spread using symbolinfointeger function
Spread[COLOR=rgba(0, 0, 0, 0.87)]=SymbolInfoInteger(Symbol(),SYMBOL_SPREAD);[/color]
[COLOR=rgba(0, 0, 0, 0.87)]Then convert the spread amount to decimal according to the opened currency pair.[/color]
[COLOR=rgba(0, 0, 0, 0.87)]Then finally add or subtract it with the stoploss price for long or sort accordingly.[/color]
[COLOR=rgba(0, 0, 0, 0.87)]This will bring the stoploss to your desired position.[/color]
[COLOR=rgba(0, 0, 0, 0.87)]Then open the trade.[/color]
[COLOR=rgba(0, 0, 0, 0.87)]Else[/color]
[COLOR=rgba(0, 0, 0, 0.87)]If you want to modify the take profit only without disturbing the current stoploss , then after finding the spread, multiply it to 3 times and then convert it into decimal and add or subtract to the current take profit price for long or short respectively. This will increase your profit target and then open the trade.[/color]

[COLOR=rgba(0, 0, 0, 0.87)]if the trade is already opened, then just use trade modify function and do the above changes.[/color]

[COLOR=rgba(0, 0, 0, 0.87)]Every changes is needed to be done manually. Ea builder do not have this level of complexity.[/color]

[COLOR=rgba(0, 0, 0, 0.87)]I hope this helps. Let me know if you do not understand any part.[/color]

Hey D.s, very thank you for this forum and the code template. I have purchased the EA Builder and found it very very useful and worth each penny spent! I have tried the basics and I am good with it but i have some troubles when comes to building EA using custom indicator. Do you have any platform or suggestions i can refer to? Thanks!

Sorry for not able t reply in this thread in time and this delay will still continue. I have a very busy working schedule as I am working on creating an Machine Learning Trading AI... So unless you have some knowledge about reinforcement learning, which may help me to finish this project, I could not interact about anything else. As i said earlier, learning about machine learning and implementing it on MT4 is taking a lot of my time.
Thanks for understanding.

Ds.

I have used 4 different tools to build EA. among them easiest one is the ea builder. I think the first post in this thread has all the links.

Thanks, I was looking at EAbuilder last night, I have not paid for it yet so couldn't get the source code. It doesn't have one of the indicators I am using, is this down to the site itself or can I add in indicators too?

Also, is it possible to add in a time parameter e.g. as I am testing a 1h strategy, what if I only want trades between 9.00 and 18.00?

I will also have a look at the other tools later today.

In the unpaid version you can download the code as an indicator. And you cannot add indicators of your own. You have to use the indicators provided by them. Custom timing is also not possible . U have to modify the code yourself for custom time.

HIGH PRIORITY INFO:

The world economy is slowing down and getting lots of spike. So any low grade automated EA will kill your account.
I hope before creating any automated trading EA you do a proper testing. Both backtest and current scenario test. MT4 back test is not sufficient.

All testing and EA creating tools i know about are mentioned at the beginning.

Hi Guys... Rather than asking me private messages regarding Ea building tips, please post it directly on this thread. For my account, I can write only one message per 24 hour , so its difficult to have multiple conversation. And others traders could also benefit from it if it is posted in the thread directly.

Regarding your question as "How to code an EA easily, which follow 2 time frame rule and movement in higher time frame determines the trading direction for intra day (purely price action) ?"

I guess in your question purely price action means without the use of any indicators, you need to find the trading direction.
Thee fact that you want an intra day strategy to code means you are interested to trade with 5 minutes to 1 hour time frames.

My Coding logic:
1. Take 1 Day time frame only as your higher time frame.
2. Analyse previous two day candle only.
3. If yesterday candle broke above or bellow day before yesterday's high or low, then for today your direction is only buy or sell respectively.
4. if yesterdays candle closes inside its previous day candle, then shift the reading by one candle to the left and reapply the process with two candles only to get the old direction which may continues. And keep in mind the probability of a good trade is low today, as price was not able to break and close outside currently.

This is a tested strategy for finding the direction with high accuracy. I have built it without coding, using the tools I have mentioned in the first page. So Just look at the chart manually and see if it suits you method after that design it.

custom indicators directly cannot be used even in the paid version. But if the logic behind the custom indicators can be achieved using the combination of the provided indicators, then you can create your EA using that logic.

Hello D.s,
In the EA builder is there a way of getting a buy or sell to be delayed from order open that takes place on the first tick of new bar at the open.
I want the order to open at low of the next bar and not the open.
Icustom signal is taken from an indicator buffer that calculates the price of the candle LOW as a signal to BUY. or opposite for SELL
Appreciate your help.
