Assistance With RSS MQL4 EA

[bmkinyua]

I have an EA that would read RSS from investing(dot)com and dailyfx(dot)com RSS feed breaking news and would send me emails as the breaking news would break. It used to work fine but has since been reporting nothing new to report even if there is news (screenshot shows the message, it is not an error but the message is false as there is news in the RSS feed).


Kindly assist check. The EA is attached.

The error message says that there is nothing new to report. The indicator prints it when the current content of the RSS file is the same as the previous one.

Unfortunately, you didn't attach the HTMLTagsLib.mqh file, so I couldn't test it.

There are new news links in the RSS if you paste the RSS links in your browser. It was working before but it stopped. Kindly assist. I have attached the HTMLTagsLib,mqh

I have a similar ea but now reads rss for economic calendar and that sends the emails fine. Would you want me to attach it so that you use it as a 'working control' for comparison?

If you add this line after the line 30 in the source code (rssFXnews.mq4), you will be able to see the server's response to an HTTP request:

Print("headers: ", headers);

MetaTrader receives the following 403/forbidden response:

It looks like Cloudflare (used by both websites) is blocking attempts to connect to the websites - most likely, considering it bot traffic.

You could try sculpting the request header or the request cookie to bypass it, but I'm not sure if it's a viable method.

Can you assist with this?

From our discussion, I had an Eureka moment. Since it is investing(dot)com and dailyfx(dot)com blocking, and I had mentioned I had another EA sending me Economic Calender news (from myfxbook(dot)com)... I simply used news RSS from myfxbook(dot)com.
Thank you very much. You can play around with the EAs for Economic Calender and Breaking News. They both work fine.

The reason for the extra effort on sending the RSS on email and notification was because RSS apps on Android app stores are not very efficient. The tend to 'sleep' and not send the breaking news as the are published, unless you open the apps then the send you notifications in bulk.

Thank you.

My final draft.
Again, thank you.

Hi Enivid,

Help with a situation where the EA sends multiple number of alerts for one RSS news tag. Can you assist stop sending multiple emails on one news tag even though the RSS link has one news item.

Take note of the repeated news. But if you go to rss link, hte news links are one. Can you help stop the multiple sending of news?

The EA doesn't check if the news has already been reported before sending. It only checks the entire RSS feed code to the previous version of the RSS feed it had read. So, if even one letter changes in the entire RSS feed, it will send everything again. For example, the RSS feed might include the current date/time - this would cause the difference between two RSS request results.

Have any ideas how I can sort this?

You could try coding the EA so that it is remembering all the news titles it gets and compares the ones from the RSS feed to only alert about those it doesn't find in its memory array.
