Taking on Excessive Risk

This seemed like a good topic for today because I've been taking on too much risk at certain points in my trading without really thinking about it - and I suspect that's how it happens to a lot of traders. My risk management mistake is failing to scale back my position after a loss if I decide to continue the trade in the same direction. This happened today as I decided to continue a long trade I started yesterday. Both trades went the wrong direction thanks to some good US CPI numbers, and according to a strict fixed fractional strategy I should have jettisoned a few mini-lots today to bring my position into the proper ratio with my reduced capital. But I didn't, ending up with a position, and a loss, that is significantly larger than it should be.

There are a few reasons I give myself for failing to scale back losing positions like this: (1) overconfidence that my system's accuracy will turn the loss around quickly and fix the problem (2) the fact that I hate spending money on spread costs, and I'd have to spend more to exit and then re-enter positions with a smaller lot size (3) concerns about sloppy execution and losing a few pips in the time it takes to exit and enter the trades. The last two reasons are somewhat valid, but the amounts I'd be saving are almost certainly smaller than what I'm losing by taking on too much risk.

In my experience, excessive risk tends to creep up on you like this when you're not paying attention, or paying attention to the wrong things, like that loss you really need to recoup in a hurry. Some common justifications for taking on too much risk that you might want to watch out for are:

• Just this once - kind of like that last drink or cigarette before you quit.
  
  
• Total impulse - you prevent yourself from thinking about it, you just leap without looking because forex is only interesting if it's a gamble.
  
  
• Good reasons for a bad idea - sure, saving on spread costs is a good idea, but not if you end up risking 25% more than you should.
  
  
• False sense of security - you set a very tight stop-loss and it keeps getting hit over and over again. In this case the thing that makes you feel safest in your trading is actually the biggest threat to your success.
  
  
• Boredom #1:I haven't analyzed my trading and I don't feel like it because it's boring, and therefore I have no idea what's too risky.
  
  
• Boredom #2: Trading with lower levels of risk is incredibly boring and way too much like my day job to be worthwhile.
  
  
• Starting with an unreasonable goal and reasoning backwards from it - I'm in a hurry to get rich and I can only make $1 million in 6 months if I take on this much risk.
  
  
• Pursuing a statistically valid but aggressive strategy like Martingale without the funds to back it up.
  
  
• Setting up an automated trading system but failing to monitor it closely and after a losing streak it ends up risking way too much.
  
  
• Misidentifying high risk events as low risk. For instance, trading on big news events can seem like a higher reward/lower risk scenario. All you do is see which way the trend is going and jump on it, right? But then there are the whipsaws, and the stop-hunting, and the various fake-outs the market likes to pull at these times, and what seemed low risk turns out to be quite risky after all.
  
  
• "Picking up nickels in front of a steamroller" - certain types of carry trading have been described this way. It's easy to focus on a reliable trickle of profits and be lulled into ignoring the underlying risks of your position. This is another example of misidentifying high risks as low risks.
  

Those are just a few of the ways this can turn into a very risky business very quickly. If you've got more to suggest, please post them in the comments...
