I don't think Xela, or any other skilled trader, would do so based on nothing more than today's profits. However, as I mentioned above, if the 2nd trade is based on one of your setups that develops later in the trend, it's based on your plan just as the 1st trade was. And that would not be gambling, would it?To allocate more toward a trade just because you are up for the day or week is not what I would do.
