Markets allow people to trade and bring liquidity to the commercial system.

Do your wins ACTUALLY mean someone else loses, or is that just your own perception?

Are you actually BEATING other people, or are your trades just more inspired than other people's and so your profits are greater.

Provided you are not stitching anyone up by giving false information or trading illegally your buys and sells are with other parties who have agreed the price and are free to enter into the transaction or not.

If you are selling a stock and someone else believes that the price is the right price they will buy. If there are no buyers then the price will have to drop. That is how the market works.

Adam Smith referred to the "Guiding Hand" at work in markets. It is all part of the commercial process that is in place that helps people to get Rich.

Thanks to all those who replied. I have since resolved my issues with trading.

All the best
