My Favorite Indicator That Helped Me Become A Better Trader

When I started trading, I quickly noticed that I am much more comfortable spotting reversals than finding conventional trend-following or range entries and to this day I am a pure reversal trader (learn more about my strategy here). However, I was still losing money and I blew a couple of trading accounts and a few thousand Dollars before I seriously started looking into why I was failing.

Once I started auditing my trades and performance, I saw that I made some pretty good trade calls but then I always kept repeating the same mistakes and I gave back my profits and then some. However, my findings during my performance audit were liberating because I saw that my mistakes were following the same patterns and although I was still a very rookie trader, I knew from the books that I had read that those seemed to be common problems. Let me briefly sum up my problems and mistakes back then and I am sure that many of you will find yourself here too:

  • I was looking for reversals, but I was often in the ‘predicting’ mode where I went short although price was still going up and I was trying to call tops before any real sign was given.
  • This then lead to me adding to a loser because I was so sure (read: hoping), that price would turn and I was misinterpreting the quality of a setup. I lost more than one account with averaging losers…
  • I was generally a victim of FOMO (Fear of missing out) and I was often way too early in the trade where I should have just waited one more candle.
  • I entered trades out of boredom when I was forcing a trade where there was none.
  • I often went for the home run instead of closing an already profitable trade, and then my winners turned into losses.

Somewhere around that time I read the trading book “Pit Bull: Lessons from Wall Street’s Champion Trader” from Marty Schwarz and it was the right book at the right time. He mentioned that he was using moving averages as a directional filter and he also talked about utilizing checklists. I had heard this all before but now after my performance audit it made much more sense and I thought that if a ‘market wizard’ was using such simple tools like a checklist and a regular moving average, maybe it would also work for me.

I then went back to the drawing board and started applying different types of moving averages and I went from faster EMAs, to very long term moving averages, until I found my perfect fit. My fastidious record keeping showed that the 20 SMA worked great – it gave the best signals and it kept me out of many losing trades at the same time.

I know, you were probably hoping for something more drastic and spectacular but you have probably heard that ‘keeping it simple’ is the way to go. And this is so true! So let me explain why I give the 20 SMA so much credit, how it helped me turn my trading around and how I use it. Today, the 20 SMA builds the core foundation of my trading strategy. But as you will see, there is nothing magic about the 20 SMA but it’s only about what you can do with it.


#1 No more predicting and calling tops

For the most part, I only take trades into the direction of the 20 SMA. This means that I only take short trades when price breaks (and closes!!!) below the 20 SMA and I only consider long trades when price breaks above the 20 SMA.

I usually start watching Forex pairs for potential reversals when they are trending very strongly and it’s tempting to enter a reversal trade too early because you want to get in at the best possible price. The 20 SMA rule keeps me out of such trades because once price breaks the 20 SMA, price has already reversed from the absolute top.

Tip: When using the 20 SMA rule, only make trading decisions when the candle has closed. Avoid making mid-candle decisions because price often shows a fake break attempt at the 20 SMA during the duration of a candle.

#2 The best entry for safe trades with the momentum

Once you start following rule #1, you can often catch great entries. If, after a rally, price starts reversing and then breaks the 20 SMA with a strong candle, you are often very early during a completely new trend.

Here it is important to think a little outside the box: there is nothing magic about the 20 SMA and it’s a pure filter-tool. Thus, we don’t look for candles that just barely break the 20 SMA, but we want strong ‘momentum candles’ that show that price is shifting from one trending phase into a new one.


#3 Better market selection

At the beginning, I made the mistake that I was only following a fixed selection of 3/4 Forex pairs, day in and day out. As a swing trader, this is the worst thing you can do because you end up forcing trades during market periods that don’t suit your trading style.

As a reversal swing trader, I should only be trading Forex pairs that are in a strong trend with high momentum and that show early signs of fading momentum. The 20 SMA is also the ultimate tool here: when I select my Forex pairs for the trading week ahead, I only look at Forex pairs that have been moving above or below the 20 SMA for quite some time and that haven’t broken the 20 SMA recently. Also, you only want Forex pairs that show a 20 SMA with a steep angle. This alone already eliminates all low-momentum and range-bound markets that don’t go well with reversal trading.

Being more selective with the markets that I trade had a big impact on my overall trading.

#4 I regained my trust and abandoned FOMO

FOMOVery quickly after I established the 20 SMA rule in my trading, I saw a major improvement in my trading. Granted, this rule alone didn’t make me a profitable trader, but I saw the huge improvement in my performance and it gave my confidence in my system.

In hindsight, I can see that this is a very overlooked aspect of profitable trading. Everyone is hoping for a trading strategy that gives them consistent results while they jump from one method to the next, adjust indicators and settings, change entry rules or take completely random trades. Inconsistent trading decisions ALWAYS lead to inconsistent trading results which then leads to more inconsistent trading behavior.

Once I started using the 20 SMA and I saw the change in my trading, I gained trust and my trading decisions became more consistent which then lead to more consistent results. When I go through my trading journal, I can see that my trades now almost look IDENTICAL and whenever I see a trade that looks different, I immediately know that I screwed up. Strive for consistency in decision making!


#5 The checklist for fool-proof trading

ChecklistAs humans we are experts at fooling ourselves; we usually always know what the right thing to do is but we still come up with excuses or reasons why it’s better for us to do the opposite. Whether it’s about diet, exercise, studying, staying sober, or trading.

Early on, I always caught myself second-guessing the 20 SMA rule and I still went before the candle close or ahead of the 20 SMA because I thought I was going to miss the move or I could get more money. Well, we all know how this ends 😉

In his book, Marty Schwartz said that he was still using (after decades of making millions as a trader!!!) a laminated checklist before every trade. I didn’t have any alternatives and I had nothing to lose, so I started utilizing the checklist tip as well and I created a checklist before every single trade with the signals I needed and things that needed to happen before I was allowed to enter a trade. It might sound silly but it’s much harder to break your rules if you see it black on white that what you are doing is wrong and when you have to actively convince yourself that not listening to your checklist is the right to do.

All those tips help me fight my biggest problems and it made me become more selective, trade way less and help me understand when my trading system performs best.

I am still not perfect and sometimes I mess up, but those unnecessary mistakes have become less and I attribute a big part of my improvement to those simple hacks.

I am not saying that the 20 SMA rule is ideal for everyone and I know that it won’t work for all types of trading systems, but let this just be an inspiration for your own trading: look at what is causing your problems, think what could fix them and then work on your process.

  1. Who understand trading MA are enough. ema 200, 21.

  2. Douglas Grobbelaar

    Here it is – I have been using this for sometime – thanks to Rolf and Moritz!


  3. Hi Rolf,

    I would just like to add that any beginner in trading should first and foremost strictly obey basic risk management rules to: 1. never risk more than 2% per trade (I’d advice 1% or even only 0,5%), 2. never ever add to a losing trade and 3. learn that trading is not about perfect entry and exit points, but all about probabilities and having statistical edge in the long run. Basic understanding of money management is far more important than any technical or fundamental knowledge for any novice trader. MM is sadly one of the most neglected themes in retail trading. Traders usually start to pay attention to it, when they’re already on the edge of disaster. If you want to have time to learn how to become mentally balanced and disciplined trader you have to protect your capital first.

  4. i really couldn’t thank you enough, the best advice you gave was to let the candle closed first. Too much noise during the intraday. It helps a lot for me to trade FBMKLCI futures. Thanks Rolf.

    This reminds me of a book Black Swan if i am not mistaken, where the author mentioned about an experiment about test candidates being shown 100 of screenshots of transitioning sketches from blank paper to a fireman. No one can identify it. But when the test subjects were only shown few screenshots (25%, 50%, 75% and 100% completion) of the transition of the sketches, most of the people can tell the artist is drawing a fireman.

    i keep losing money when i trade the intraday futures and also suffering from FOMO.

  5. Hi, Rolf! Fine article, is not enough for me such trade while I trade without loss, but also there is no profit. I hope to me very much your approach to SMA20 will help. Thanks for good article!

  6. hi, when we look for that price must cross 20 SMA , is it for weekly chart or daily chart.
