Success; so this is a 5 minute chart of yesterdays SPX. I had entered pre-market open (14:30 here in the UK) so already had a reasonable profit at market open.
As you can see, the market rose quickly from the open, which is when I scaled in as I figured this was a high probability trade. I exited all trades by around 14:39 at around 4308. Most started at about 4301.
The market continued to climb after this, but there was enough hesitation that I thought it best to get out around there. I know from experience that there can be sharp reversals near the start of trading even after a strong rise.
I did enter a couple more single bull trades for scalps after this before deciding that was enough for a while.
So none of this is bragging (I only made a few pounds anyway). I know full well that the trades could have failed, and in that case I would have exited quickly. But sometimes you just know that you have hit a sweet spot, and chances are very good that the market is moving up at least for a while. It seems to me that in those situations, scaling in can be a useful addition to your trading skills.
Incidentally, the chart also shows one of Al Brooks ideas in action of scaling into losers (don't try this at home kids, unless you know what you are doing).
After the peak at around 4320, the market pulls back quite steeply, and then rallies again to 'test the high' as Brooks has it. It is in these kind of situations that he thinks scaling in to a loser (if you had bought at the high say) can help avoid a loss.
If you are nimble and scale into a second trade at around 4314 say, you could end both trades at around 4317 and break even. I have managed to do this successfully a few times, but you have to watch the trades like a hawk (or automate them) to avoid the risk of a big loss. The key is the price action; I think Brooks is right, that there are few V shaped market moves after a strong trend, usually the market will test the previous high to some extent before moving decisively in the other direction (or occasionally the original trend will continue; more oftenthere will be a trading range).
Brooks seems to recommend holding on to break even on the first trade, and make a profit on the second one, which seems a bit ambitious to me. Quite often the market will get close to the previous high, and then plummet fast, as presumably lots of traders are waiting to get out of losing trades at this point.
A final point here; the sharp fall from 16:15 onwards looks like a classic Lower High Major Trend Reversal in Brooks speak. A break of the bull trend followed by a test of the high, then a decisive move in the opposite direction. I did guess this might be the case at the time, but hadn't the nerve to trade it.
I know that there are mixed opinions about Brooks, but his books and videos have convinced me that there is at least something to this technical analysis lark. It is a very inexact science (as he fully acknowledges) but there seem to be enough patterns that repeat over time that might give an edge. I doubt that anyone else covers the ground as exhaustively as Brooks. Just keep well stocked with coffee when watching his videos (I have fallen asleep many times). His rather monotone delivery though is a welcome relief from the more frenzied charlatans so common on youtube.
