getting price/volume data in MQL5 (or 4)

 

First of all let me say that I am entirely new to MQL programming. But I'd like to know how you can access previous price/volume action to do calculations with it. I think it must be something like this (taking the price as an example)i = price

i = 0


if (price[i] < price[i + 1] && price[i + 1] < price[i + 2]){        // price[i] is the price of today and price[i+1] is the price of yesterday


send signal

}


Can anyone please translate this order to MQL, or give a good link.
