Placing Oders

Use the same concept for 100 trades at the end, you will notice that using a stop order (treding trading) helps you to have a higher probability of winning
You will not reach the target by buying/selling the close, especially when bulls/bears get disappointed and can't exit on breakeven

I have done a automatized testing for different strategies over several years of data.

One way to have additional profits in automatized strategy testing has been to buy with limit order from 5% pullback, instead of stop order above/BTC/STC.

Limit order entry on 5% PB becomes almost always filled, but gives sometimes bad fills that would not happen if you would have used Stop orders above/below. So it will make wins bigger about 5% but decrease win % of your trades causing more SL (so it depends your strategy win % if it is productive or not). But compared to other entry styles in my strategies, it has leaded statistically to couple of % better profits.

Probably Al Brooks does not propose that way, as you have to be quick. You need to have automatic marker on bars or measure each bar to see 5% and place limit immediately the bar closes. Computer programs can do that, but it is hard for humans... Making the equation in real life worse than this automation gave for me. 

Using bigger % that 5% PB for Limit orders has leaded to smaller profits, as too many good trades has not become filled, but all bad trades whose would not have been filled with stop order becomes filled, making that kind of entry model worse. In strong closes you lose trades time to time with 5% also, but not too much. With 10% you will miss too many of those.

I personally used that style after my studies, but nowadays really rarely. Trading is not easy and with this style you get one complex and time critical thing more to your trading, getting your concentration out from trading, causing additional risk for possible mistakes.

--> My proposal, based on statistics... Do what Al Brooks teaches...

If you want to try to optimize to get biggest winners, do not go beyond 5%, as at lease based on my strategy testing of thousands of trades over last 10 year data in different market conditions... more than 5% makes you just to lose more.

ps. This is also related to strategy you are trading, these statistics are based on my strategies, whose I have been able to automatize.
