I say the S&P 500 will top at 2925-2930 and we will pull back 9% from this level I will allow 1% deviation on the trade so I will consider this top void if we on a closing basis are above 2959.3
dude. stop calling tops! Long ago, I had that mistaken disease. Now I trade what I see and not what I think. Make more money and lose less money. Maybe it will top soon or maybe not. Doesn't matter to us traders.
Just look at it as a stop loss. You use them too. His point is, that if he is wrong only by a few points (let's say the real top is at 2935) he is practically right, but you could call him out being technically wrong. Thus the wiggle room.
