Disclaimer two: For those of you who get to wear the particular hat and may both buy and sell on either the bid and ask in whatever your favorite market is then another does not apply to youpersonally, and you'd already know and understand that the following anyhow.

Yin

Forex = Zero-Sum

Reasoning... If one person buys it is because another person sold. If one person sells it is because another person buys. Volume changes from one party to another. Money vanish or does not mysteriously appear. It's currently going someplace and to someone/s. The brokers too, and ESPECIALLY.

Thinking about the movement of currencies between all parties (buyer, seller, and brokers) then trading is zero-sum. Money is neither magically created nor dropped, and all cash that enters the market flows throughout the market and leaves the market.

Yang

Forex = Negative-Sum

Reasoning... Should I buy or sell, and the price doesn't change, and that I then shut my position without the price ever ever changed whatsoever I lose money as a result of spread and broker charges. I am constantly buying and selling in the bottom price. Even if the price does change before I close a position I'm still losing the disperse. To break-even on a commerce that the price should move the space of the disperse within my favour, and every trade started is immediately at a loss and will only become profitable after first moving in the desired path the value of this spread plus 1 extra tick.

From the perspective of just the individual trader and this trader , then trading may only and IS only NEGATIVE-sum. Every place begins at a loss. Money placed into the market can not quickly be returned to the trader by shutting the position due to the spread and the brokerage charges embedded inside the disperse or as an external charge.

Conclusion: It's all about perspective. Neither perspective will make you less or more profitable. In reality, understanding and knowing the preceding will do nothing for your account. Arguing about it is even less effective.

So, can we all just agree that it is all about perspective and from that viewpoint you think about the flow of cash with regard to closing and opening trades? Please? As a whole, trading is zero-sum. Concerning a traders account then trading is negative-sum. Both are correct. Neither make a difference to anything else.
