meta trader questions

Hello FF community i'm new here and i have some questions albeit basic to many but to me a little complex; here goes:

1. I trade multiple accounts and use some EA's is there anything in existance that allows one to trade multiple accounts through a standard terminal, NOT MULTITERMINAL that faciliates EA's?

2. I like to look up previous weekly/daily/monthly charts however as of now the only way i can do this procedure is by scrolling with my mouse and turning of auto scroll so it doesnt get put back to current period...with meta trader there's gotta be a better way to just simply punch in dates you want to see and it comes up...am i right? is there such an indicator script written for this?

I appreciate any and all responses, and i wish everyone a happy and a safe 4th and a wonderful summer for everyone else

Don't know about EA's but if you want to go to a specific date just press Enter on your keyboard. Then in the down left corner of your chart you'll see a box where you can type the date you'd like.
The format should be year.month.date
