How does iMA() on other charts work?

[Lord Odin]

Hello Community,

I would like to add a  buy condition to my Trend following EA, that would be executed by ticks on the EUR/USD chart, but ONLY if the iMA() of some other symbol meets my requirements. I know that iMA() can take whatever symbol you specify for it and that I should run the EA on the EUR/USD chart in this case, but let's say i want to take GBP/USD as conditional symbol, and put period of 14 days. Will it take the 14 days of GPB/USD prior to when the tick on EUR/USD, that fulfills the condition of entry, has occurred ? In other words, does it work just as if it was conditioned on the same chart, but the data will come from the specified symbol in its arguments? 

Thanks in advance.

Best Regards.
