the MM's do that to reset the TREND INDICATORS ON TRADING SOFTWARE.
Turns the signals from BUY BUY BUY to Neutral or SELL SELL SELL.
It's a game.
That's obviously a bad price which was HUGELY outside the current market.
The print should be taken down/off the tape, and then the charts won't be messed up.
But they won't. It's hard to get a trade price changed on these.
IT's a Pinky... so they don't care.
Cheers and if you can get the priced changed,,, THANK YOU.
