I have not and never would trade that way.

I will only trade if the signal is there.

I will always trade in groups of 3 or 4.

So I have no thoughts about adding more contracts to a position. Because I don't trade that way.
And actually think it is a supid way to lose money?

But of course I always add more to new positions as profits are made etc.

Like if I am trading 3 contracts per $5000.
Once I get to around $15,000. I will then trade 6 contracts and move around $2500 out of the account.

But multiple contracts is all about trade and money management.
