Add up how many open lots there are in MT4

I need someone that can write a small indicator that would tell me how many "lots" are open. This is done by loop through all the open trades with OrderSelect() followed by a call to OrderLots() and add up the total. Its a very small project, i just don't have the time to try and figure it out myself.... but willing to give someone a rating boost if they do a good job :-) In the TOP right of the chart it should display: Open Lots: ###/### (where ### is the number of open lots). This should be reported in Standard lots & Minis Eg: 6.2 Standard lots would be 62 mini lots The font size and color should be configurable through the properties of the indicator.
