MT4 EA Candles History

[fxbusinessacc]

Hello,

 I have an EA that needs to get all M1 bars currentyl in the server for a symbol. How can I achieve that?

 

Thanks

1) Either use CopyRates() - it can be used in MQL5 as well.

2 ) Or you use iOpen(), iHigh(), iLow(), iClose() as off the oldest Bar (=Bars-1).

Read in the editors reference (F1) about the various functions and take advantage of the examples.

I used copyRates as you suggested for M1 bars. I can see in the client terminal that the oldest candle is 07/12/2016.

When calling the CopyRates I get only 2112 candles which the oldest value is yesterdays.

1. When you open a chart (copy rates) and don't have any history, you get about 2K bars from your broker for that TF.
2. Here's how you can get all available from the broker.
   • Most brokers only have 32 or 65K bars of history per timeframe. That's 45 days of M1, 2.5 years on M15, etc.
     
   • Quickly DL all available history from your broker: Problem loading historical data - MQL4 forum

Yes I know about downloading from History Center but I dont want that options since it is not automated.

I also know that they keep data for 45 days for M1s. My question can I get these using an EA? Or there is a limit

You can use ChartNavigate to automate the process.

It isn't the most elegant solution.

Thanks.

 

Apart from the ChartNavigate there isn't any other way, is it?

Not that I am aware of, at least in code without using DLLs.

Happy to proven wrong though

My post was downloading from your broker. You can't spend the 15 seconds per timeframe to get initial history, but you'll spend days trying to automate it?

Dude it seems that you did not understand the question. Problem is that the EA cannot retrieve them.
