Think about it some more Kinsy and you may realise that it will not hurt you at all - the only difference will be the way your trades are represented. If you have a signal to sell, you sell on FIFO just the same as you would with a hedging allowed broker, and if you have a buy signal, you buy. Neither will it effect the ability of traders to use grid systems or any of that crap, you input your orders just the same and you'll end up in the same situation in the end. If you wish to contest this, break it down for me here and if it works out (which I doubt it will as it is a tautology) I will eat my words. The only difference is that it stops brokers charging you for positions you do not actually own. I am all for free will and freedom of choice and all that libertarian nonsense but there does appear to be a simple misunderstanding of the mechanics of trading that is endemic amongst retail traders.
