Hello again, and apologies for this blog's recent suspended animation. For various reasons hinted at above I decided to give forex a rest for a while - but I'm now back and have just made my first foray into live trading the EUR/USD again.
The principal reasons I took a break were:
I was frankly a little bored and disappointed with the progress of my EUR/USD trading system. Out of impatience with its performance, I'd convinced myself it didn't actually work with real trades, it just looked good in backtesting. In fact, I ended up questioning the entire idea of backtesting since it offers absolutely no guarantee your trading rules will work into the future. So I decided to give it a break, and maybe come back in a few months, plug in the new data, and see if my system would've actually made decent trades in that time.
Around the same time, largely because I was disillusioned with my own trading system, I convinced myself carry trading was by far the best way to trade. So I devised what I thought was a very clever hedging system using the USD/CAD to balance the volatility of the carry trader's beloved GBP/JPY pair. But unfortunately I decided this just before the GBP/JPY carry trade experienced a giant melt-down that demonstrated how little I know about carry trading or hedging. So I got burned. Thanks to my stop-losses I didn't get wiped out, but I did get scorched pretty badly. (Did I mention I also broke my own trading rules by taking on way too much risk? Well, I did. And it was dumb.) In case you're wondering what a carry trade meltdown looks like, here's a picture. Congratulations to all the GPB/JPY shorts out there, it must've been a fun couple of months:

But there is some good news after this tale of burnout and reckless trading. As I mentioned, I've been letting my trading system sit idle for the past few months while new EUR/USD price data piled up. This new data was the raw material I needed to effectively forward test my system and see if it actually produced real, profitable trades, not just pretty pictures of historical backtests. When I plugged in the new data earlier this week, I was very pleasantly surprised: my system had racked up a very steady, consistent, profitable trading record while I was ignoring it. Which is why I'm back trading (and posting) again.
One of the trading risks I've described before is the desire to fiddle compulsively with your system, even when it's doing just fine as it is - the "If it ain't broke, don't fix it" problem. Since I'm a bit of a compulsive fiddler, my challenge now is to find something else I can fiddle with to keep me from breaking what isn't broke. One thing I've been wanting to learn for a long time is how to program
Metatrader to trade my system automatically using their MQL programming language. I suspect it'll be quite a challenge transitioning all my trading rules from Excel to Metatrader - but if I can get them automated it'll save a huge amount of time over the long term. So if there are any experienced Metatrader programmers out there, any advice on getting started with MQL would be much appreciated!
