can this survive big news which can result in big drawback?
A good question indeed. For me, the answer is YES and NO and that very much depend on your settings.
If your settings works well, then YES, it could possibly survive during big news (but not 100% guaranteed though because market is always changing and could be very unpredictable at times). Therefore, to test your settings you would need a good amount of time to test them out for long term durability of not just days but months and years.
However, if your settings don't work well for you, then your account could easily get blown at any point of time.
All EAs in my humble opinion are risky at times. Therefore, in regardless of what EA you choose or use, the KEY is to find the settings that work well for you. The other factors that also important are as follow:
1. Your Account Balance.
The bigger it is, the better and safer you could be
Note: that also depend very much on what settings you used. Even when you have millions of dollars put into your account, yet when using the EA with a wrong lot size (such as 0.1 lot for $100 standard account) or any other wrong settings, your extra huge and big account could also get wiped out in no time whenever the market suddenly turned crazy or has become extremely volatile at times).
2. Leverage
The bigger it is, the better and safer you could possibly be.
3. The Type of Account that You Choose
If you have larger account balance like $1000, $10000 or more, then maybe you could use standard account, ECN account or low spread account as you wish to. Otherwise, if you only have smaller balances such as $500, $100, $50 and etc., then I think you've better use a CENT account. Otherwise, I don't think you could survive for very long with this EA or/and many other EAs of your choice.
