Correct Martingale 2

I've got an expert advisor with a martingale function.

This expert is designed to work with several currencies at the same time.

I'm looking to 2 new functions:

1. If i use the same magic numbers on all currencies, i want the martingale to work as one. For instance, i loose on the EURUSD, and afterwards a USDJPY occurs and it open as a martingale as well. If i use different magic numbers it works as it should. For instance, i loose on the EURUSD, and it just open a new trade as martingale on EURUSD;

2. I don't know if it is possible, but my strategy doesn't open trades very often. The problem is, that sometimes it opens a trade on the same currency just once a week. My PC restarts, and it looses the martingale level. It should keeps in memory even after a restart.
