Someone can allow 30k loss with only 60k account

i don't think that is a good idea. 30k sl is equal to no sl. that is dangerous.

I think it's OK if the system can bring you 30k profit before the 30k loss happen.

Hi, depends on that someone and their strategy. If that is part of their trading strategy, that an emergency stop loss is set at 50% of acc. The chance of hitting this SL should also be less than 50% per trade basket. Finally, it will take 100% gain after just to reach Break Even!. Keep that in mind

That really depends on how possible it is for that 50% to be hit.

If your 50% risk is dependant on natural gas still existing in 3 months, and you are making good money on the trades, then I really don't see a big issue. If your trade is dependent on the price of natural gas being over $2.6 then you have a massive problem.

thank you for you guys reply.
but i don't agree with you.
i think traders shouldn't set the sl so big that will break their account if they had loss twice .
