EA on more than one timeperiod & pair

Hello,

I am a java programmer getting used to MT4. I have a few questions regarding MT 4. If anyone can answer them, I'll greatly appreciate that.

 

1. I wanted to know how can I run one EA on more than one time frame. e.g. if I want the ea to go long when when H4, H2 and H1 Parabolic SAR is greater the opening price of the current candle. How do I do that?
2. I'm guessing if I want the above EA to run on more than one pair at the same time, is it just a simple matter of drag and drop the ea onto the chart?
3. How do I display H2, and H6 charts in Metatrader Software?

Thanks in advance for all your help.

Regards

use the following to make sure the operation on works on the desired currency. use multiple charts and put the EA on each with a diff MagicNumber.

if(OrderMagicNumber()==MAGICNumber && OrderSymbol()==Symbol()){....}

If you have a strong Java background, then you should do just fine with MQL.

1 - You can always pull data from various timeframes within a single EA. Virtually all indicators have the "chart" as a parameter. Most code examples use NULL for the current chart, but you can pass something like PERIOD_D1 or PERIOD_M30

2 - Similar solution to this one. Most indicators use Symbol() as a parameter, but you can pass the pair name as a parameter.

I'm positive of these two answers because I've created a scanner based on these principles - I scan multiple timeframes and multiple pairs off a single EA, no need to deploy to multiple charts.
