Quick reply for you:
Where you are has no bearing at all on MT4 platforms, e.g. the broker or "platform" time is the same regardless of where the computer is.
You have Alpari UK, and need not deviate from the 7 AM timeframe, since that platform is constantly one hour later than the UK time.
We speak of 6:15, 6:30 etc in reference to UK time, because that is when FMT is intended to trade.
Some prefer to trade at three separate times, others prefer to trade at whatever Mark's current setting is. That is strictly a personal preference, but is usually based on a lot of study.
If you want to stay with Mark's program for the moment, (and I might recommend that until you understand everything about trading), then just keep your trade where it is on your Alpari UK platform at 07:15.Then at least you have something going while you explore your options.
My test and forward results always show the 06:15, 06:30 and 06:45 because that is the actual UK time at which the trades are taken, and because in this silly business there is no central exchange and most brokers operate on their own clocks.
I repeat, stay at 07:15 on your Alpari UK platform and you will be doing exactly what Mark is doing. Look at the PDF that came with your EA and different broker times are explained there also.
You might also consider going to Babypips.com and taking all the lessons on FX trading. It is not terribly demanding, and brings great benefits in a very focused way.
Good luck
