Capital losses and gains in trading? Some rules? You never know where the tax would catch you it seems. I understand when the tax is law but there are some more complicate catches. I would know all this if they would be so nice to let me do it for some time as in the game so everything I do can be errased.
The capital gain is when you subtrac the amount you sold from the base of your asset. Capital loss is derived from it. The tax would catch you where you sell things you got. You do not pay the tax before the security is sold and profit got. That is the way you can gain.
