Second(s) timeframes on your MT4

New comment

Ynal Al Khalil 2026.05.29 19:59

this script converts the chart's ticks into any Second(s)timeframes !!!

the Script works only for XAUUSD, you can modify it to work with other pairs or other names of Gold pair.

Example custom periods:

S10

S15

S20

S30

S45

S50

Once the Second(s) chart is generated, you can apply almost everything you normally use on regular charts:

✅ Templates ( .tpl )
✅ Indicators
✅ Expert Advisors
✅ Objects & drawings
✅ Trendlines
✅ Fibonacci tools
✅ Moving averages
✅ Oscillators
✅ Custom indicators
✅ Price action tools

Enjoy the Script !!

Ynal Al Khalil:

The forum is for mostly questions regarding the use of mt4 and mt5 AND the reporting of program bugs. I suggest that you place this on codebase since your post is not in response to either of these.

your post is obviously fishing for sales. if i understand the sellers agreement that you and I both agreed to when we applied for seller status, we cannnot post on the forum unless our posts are is in response to either of the above.

In my experience, it's a lot easier to search for/find a CodeBase Publication than an individual Forum thread. Why not post it in the CodeBase and then watch the count of views and downloads climb?

In this way, you can help more traders and legitimately increase your user rating faster.

By the way, is there a reason that your file name and code comment are limited to XAUUSD?

Likely due to the incorporation of an external file─same as the Market validator. My bad, for not seeing that in your code previously.

FYI, you can post it in the Blog section of your user Profile too which is relatively unrestriced.

Hello, I came across your post on FXBlue and wanted to express my sincere thanks. However, the script currently only works with XAUUSD; could you "unlock" and rewrite the source code so it works with all instruments? For instance, I trade gold on an Exness Zero account where the symbol is XAUUSDz rather than XAUUSD (without the 'z' suffix). Please rewrite it. Also, if possible, could you create versions for both MT4 and MT5? Thank you very much.

till the end of this week, I'll make the modifications you requested.
It is a piece of cake !!!

Ryan L Johnson 2026.09.01 21:26 #8

Just delete:

   if(Symbol() != "XAUUSD")
   {
      Alert("Attach this script to XAUUSD only.");
      return;
   }

and replace:

            "XAUUSD Seconds Chart Generator\n",

with:

            Symbol(), " Seconds Chart Generator\n",

Because Symbol() is used throughout the rest of the code. It wasn't really hardcoded for XAUUSD.

The on-point rule is Rule #16 of the Rules of Using the Market Service:

"16. The Seller shall not use spam to promote Products on the Market both on www.mql5.com website and via third-party services. Upon detection of spam, the Seller's account will be blocked and all his or her Products will be removed from the Market."

Having quoted that, it would be rather self-defeating for a Seller to post the source code of her/his Market product in promotion thereof. That is to say, who would rent/buy an ex5 file when its mq5 file is free? I should note that I didn't inspect any FXBlue content for potential spam. FXBlue certainly is a third-party service but again, if nothing is for sale, no Market product exists─the Rule doesn't apply.

On a related note, there is a more general rule against self-promotion, e.g., a Seller posting a profitable backtest report. In contrast thereto, posting a simple script is merely giving away a utility.
