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?

I already tried to post this in the CodeBase,
they didn't publish them !!
I don't know why,
the same with another post (Unlimited MT5 trades copier using two Python scripts)

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.
