Dislikedbtw, we often see conversations about systems getting "ruined" by sharing. this stategy presents the perfect opportunity to explain why a system (that exploits an inefficiency) does in fact get ruined by sharing....
lets say a bunch of start exploiting this (which will most likely happen LOL). we would all be setting up some sort of limit-straddle on the crosses. at first, all of us will get filled on our limit orders. but as more and more people join the party, only the people with their limits closest to the market will get filled, because there is only so much liquidity in this little whipsaws that occur. eventually we will start to step all over each other, everyone putting their limits closer and closer to the market, in order to get filled. eventually this collective behavior will essentially "flatten" the whipsaw, because there will be limit orders straddling the market so tightly. then poof, the inefficiency is gone
i dont know how long this inefficiency will be here (or if it even exists, only real life trading will tell, and fills will be the key), it could be months or years, you just have to get in while the gettins good. the value of this inefficiency is exactly equal to the liquidity that is present in the whipsaws on the crosses. once the liquidity becomes very low, the value is also gone.Ignored
I think you're right in theory about too many traders ruining a system.
I don't agree in practice, at least with forex.
If everyone that reads this board goes out and does this and tells everyone they know and they start doing it too, it would be like a drop in the ocean compared to the total forex market.
Forex is just too big for the traders of any particular system to have an effect on it.
My humble opinion and I may be wrong.
