Modify a MT4 expert advisor

I found this free expert advisor in the net its name is Hedging Strategy (4 pairs), (actually 6 pairs) and I really like it, because it suits my type of trading. There are some things that should be improved, however, and the changes I ask are these: 1. The expert at present is designed to operate in a single instance. I have tried to add a comment ad a magic number in the code using different ones for each instance, but in comments shown on the chart, the profit is always referred to the sum of all open instances, and not to each individual chart / magic number. In this way trades are closed only when the sum of all open instances of multiple charts reach the profit indicated in the settings. What I want is that each instance is independent to the other ones, using a different magic number, and that profit is separated for each magic number, in order to manage separately each one. 2. At present, if the conditions are right, the trades are opened at the start of a new hourly candle. I wish that in the settings one could choose which type of candle wait for the opening of the next series (1,5,15,30 or 60 min). 3. It’s also necessary to change the profit setting. Currently it is not very clear, if I want to close with a profit of 20 euro I have to enter in the settings "Profit: 2.0"; It would rather that profit was indicated in percent of the Equity. I would also like to know what exactly is the "Delta" setting and what is the use. That's what I need right away, if you accept the job I ask you kindly to be available for future changes.
