3 different EAs on the same platform? Shutting down computer on weekend?

I have three different EAs, which I would run on a DEMO account starting Sunday when market opens and will let them run for a month and evaluate the results. My question is, can I run all three of them on the same Metatrader and on the same account?

The EAs which I am going to test are:
1) FxNewsBot - For fundamental trading
2) WallStreet EA - For technical trading
2) Forex Combo EA - Also for technical trading

Some of the charts which I will place these bots on are same charts such as EUR/USD, GBP/USD etc. Yes, I cannot place two EAs on the same chart, but I will open different charts of the same currency pair and place those EAs.

My question is, is it okay to run three different kinds of EAs on the same account and same Metatrader?
Also, On the weekend can I shut the computer down? What if I reboot the system during trading week, will the EAs 'forget' the open positions? Or will they resume from where they left at?

hi raviluke,

you can run all 3 EAs at one Account and using same currencies if each EA has his own Magic Number for identifying his trades. For this there is an input for this within settings for changing. If yes, go and let them do their work.
Yes, you can shut your computer down.
EAs will recognize their trades again after restart because of their magic numbers..

always good trading
