Quote from Walther:
Price went down from opening and 9:45 was the best time in the morning to take a trade.
Yes or no ?
Best time to take a trade? No way. Was their a trade to be made? Of course, but there is always a possible hypothetical trade to be made. Doesn't mean anything.
Now, notice you never specified a direction. Hence at any given time you can be 66.6% right since the price can only go 3 ways, one of the directions being worthless.
See, I'm looking at the chart from friday and what you called out was pretty much crap. Let's say I went long at 9:45. At best, and I'm being very optimistic, you could have made 4 points. But you would have to sit through all those ridiculous chops. That's a shitty move. A good trader would have to ignore most of his discipline and experience to sit through that crap. Realisticallly, a good trader would probably be out within the second chop and make 1-2 points. Aight, not horrible or anything.
But Friday had several moves and possible trades, some of which were just beautiful, especially the 1 PM drop. Of all the moves, you called out the worst one. So even if you were semi right by calling out 9:45, it's nothing special comparing to the whole day. You also never specified long or short and when to get out. BTW, you could have made money either long or short from 9:45 depending on your hold time. Does not take any skill to call plays like that. Reminds me of mrmarket's forever hold strategy.
But you did call out a intra-morning low, even though you were vague about it. So maybe there is something to your mathematical approach. If you lost the a$$hole attitude and actually listened to your critics, maybe you can get much better.
