You Buy at Ask and Sell at Bid . . . the chart is drawn by the Bid price.

interputure, you can set MT4 to display the Ask line as well by opening the chart properties (right-click anywhere on chart and select 'Properties...') and checking the 'Show Ask line' checkbox under the 'Common' tab (you can also choose that line's color under the 'Colors' tab).

You buying price will always be higher. after you pips rise above your buying price then you start making a profit

It depends on the market trends and as for more info on buy, sell check out some of the free online resources including babypips school of pipsology and FF threads.

Thanks everyone!!!
