MT4: script to change all chart timeframes at once

Hi Cja,
Many thanks to you. Really appreciate this.

Cheers

Hi cja,

Fyi, I attempted to use your "Symbol Changer MT4.ex4" script, but it quit prematurely before changing all of the open charts. I opened an old profile that had 25 charts with several symbols and timeframes for each. Only a handful of charts updated before it quit prematurely. It might be that I was exceeding some MT4 limits with that many charts open, and/or some of those old charts were out-of-sync with my current Indy versions; I saw some suspicious error messages, including some that said 'bytes of leaked memory' (for my own indicator). I decided to try again by closing all the old charts and starting again fresh.

With only 6 new charts open (3 symbols, 2 TF's each, not all the same), the script *almost* worked. I dropped it onto an AUDUSD chart. I left the "Symbol" entry as the default, "EURUSD". It changed all the charts except the one that I dropped the script onto. A popup message occurred:
Do you really want to stop script 'Symbol Changer MT4'?

Whether I say "No" or "Yes" makes no difference... the "AUDUSD" chart that I dropped the script onto is never changed to "EURUSD".

If on the other hand I drop the script onto a chart with the destination symbol (e.g. EURUSD), then of course that chart is already the proper symbol so it doesn't need to change. The script runs to completion and it successfully changes all the other charts.

My requests:

* Fix this bug that it does not change the symbol for the chart the script is dropped onto.
* My preference would be to eliminate the default destination symbol choice of "EURUSD", and just leave it blank. If left blank, I can always open 1 chart that I want, then drop the script onto it to update all charts. If it's not blank, then I am always forced to manually override the "EURUSD" choice to either blank, or type in some explicit choice. IMO, leaving it blank is a little bit better default.

* Enhancement: Offer a new Input variable to "Delete all chart objects?" (default 'true'). Why? If I have opened a spread of AUDUSD charts in which I have drawn custom objects (e.g. Trendlines, Pitchforks, Fibos), then these objects are based on the AUDUSD prices and times. When I change all the charts to another symbol, e.g. EURUSD, all these custom objects are irrelevant and should be deleted.

My assumption is that any objects created by the Indicators on each chart will regenerate the objects when the chart symbol is changed (so obviously it's important to delete the chart objects before updating the symbol rather than after).

* Enhancement: Offer a new Input variable to "Change charts with only this symbol" (default blank, meaning change all charts, not just those matching the symbol). I think it would be useful to be able to change only a subset of the open charts to a new symbol name.


Thanks for considering these requests. Your choice as always. When I get time, I'll be able to write such a script myself if you don't get around to it, but I thank you if you do.

CORRECTION!

I was apparently wrong where I wrote: "Whether I say "No" or "Yes" makes no difference... the "AUDUSD" chart that I dropped the script onto is never changed to "EURUSD". "

As I'm retesting it now, when I get the popup that says: "Do you really want to stop script 'Symbol Changer MT4'?"
... if I answer "Yes", then *after* I do so, then indeed the last chart (which is running the script) will in fact update to the new symbol. If I answer "No", then it won't work; it leaves the last chart unchanged. I wish there would be a way to prevent this popup, but I suspect there isn't, other than writing the script instead as an EA or indicator, which is probably not worth the bother to do so.

I checked the code to see why it did not change all the open charts and realized I had left the chart number as 10 which is the number I had used during testing. I have updated the code and also set the default Symbol as blank which is a good idea. I have noticed if you drag the script onto a chart and leave the Symbol blank so it uses the chart Symbol you do not get the script pop up message. I had a quick look at your other suggestions however found that it was not going to be a 5 minute job so I will put them on hold and have look when I get more spare time.

I have just re-posted the scripts for some reason they did not upload the first time.

Many thanks

hello i need help, i need to change/shift or what method to get same candle stick broker B to broker A

You can't change the broker server time

Check the Specification on each Broker for the Trading Times

Use 1 hour chart, they should all be the same, near enough for trading Gold

Good Luck

I'm Consider the same issue and can't solve it
