Arguably the single most important skill a trader needs to master in trading any market is to cut your losses short and let your profits run. This is simply another saying of managing risks and maximizing opportunities. However, this is easier said than done. Ever tried to cut your losses short but only to see the price run in your favour soon afterward? Or, that you've built a sizable and profitable position only to see it turn into a loss? As with much of other trading skills, managing your trade is not an exact science. That is why you need to have probabilities in your favour on every step. You enter a trade because it is likely to be profitable. You exit a trade when it is not. If you can apply this axiom on every trade you do, it is likely that you will be profitable, with all things being equal. So what does this have to do with cut your losses short and let your profits run? In this post, I will discuss one trading strategy which I use to do exactly that. The key to this strategy is divide and conquer. Instead of taking one trade for each position, consider taking multiple smaller trades by scaling in and out of a position. That way, you can have more freedom in your trade by using your position size to your advantage. Here's the gist of the strategy and the rationale for it. The rule is simple: increase a position by scaling in as the probability of success increases; and decrease a position by scaling out as the probability of success decreases. One way to do this is to add on a position as the price breaks support on a faster timeframe. You keep adding on this position as long as your trade setup (on a higher time frame) is valid. At the same time, you limit your risk by lowering the stop of your previous trade to breakeven. That way, even though you are stockpiling a position, the overall risk stays the same. This is an essential step in the technique. Otherwise the risk would just multiply. It is as much managing the entries as well as the stops/exits. Let's put this into perspective with a real-world example. Figure 1 shows the support levels for my EUR/CHF short on a 3-hour chart. I identified this trade using my FTC setup on the daily chart. The failed break above 1.4800 on January 14 was the signal for entry. I took an initial short position risking 0.20% of my account as EUR/CHF reverted back below 1.4800 (first support, not marked). Then I kept adding on to this position below 1.4787, 1.4761, and 1.4742 supports as shown in Fig. 1 with the horizontal dashed red lines. On each subsequent new entry, I move the stop on the previous entry to b/e. I only risk 0.1% on each of these additions with half the position size after the initial entry. As I keep adding, I keep moving the stops one step behind. So on my third scale-in, my initial stop have locked in some profits at a price level between my first and second entries. Figure 2 is the same chart but with the actual filled orders (yellow triangles) and current stops (red lines) marked. As you can see, I have effectively accumulated a sizable position size in this short while limiting my risk to just a fraction (0.2% versus 1.0%) if I were to enter my maximum size all at once. Furthermore, my confidence and probability of this trade increase gradually as I see the short-term support levels break one after another.

First of all, this strategy is mostly suitable for trading setups with an expected high reward/risk ratio. You might not want to use this for a range trading strategy as there's probably not enough price move to break the trade into steps. Secondly, this technique is mostly for an automated system or longer term manual strategies (hours or more). Just so you have sufficient time to manage all these extra work without adding on an unnecessary amount of stress. Lastly, an obvious downside to this approach is that your account will take a hit from the spreads and commissions for each move. So do take those costs into account in building your own adaptation to this concept. Now that I've discussed my scaling-in technique, what do you think? Update January 22: I've closed this position and it turns out to be one of my best trade ever.
