One of the best things about the new metatrader 5 platform – as I mentioned on a previous post – is the extreme quickness in which backtesting and optimizations can be done. It is remarkable how I can now do a 200 run optimization in less than an hour while previously it took more than 5 or 6 hours and even 24-48 for certain trading systems. After porting Watukushay FE and enjoying this very fast simulations capability I decided that it was time to try a multi-instrument approach for this freely available trading system. Certainly I had donde some experiments before on the USD/CHF and the GBP/USD but I had never been able to try as many combinations and settings as I wanted to due to the inherent slowness of MQL4 based backtesting. On today and tomorrow’s post I want to show you some of the results of my studies on several currency pairs for Watukushay FE and how these results show us a very wide and unique perspective about the Watukushay FE trading system. For those of you who do not know anything about Watukushay FE it is a freely available trading system I coded available at http://watukushayfe.blogspot.com.

It is important to note here that I coded Watukushay FE based solely on my observations of the RSI and trend behavior on the EUR/USD and I had never thought about making this expert trade on other instruments when I first designed and implemented its logic. It is a fallacy that a “good system” should work on “all” currency pairs as it tackles a “vital aspect of market psychology” since different pairs have different trading makeups and volumes which make their particular price action very different. Pairs that people may regard as similar such as the EUR/USD and the USD/CHF are in fact tremendously different with many systems that work on the EUR/USD failing to work on the USD/CHF and vice versa. Some of the reasons why this happens include bank intervention, liquidity, volume, trade deficit difference, etc.

However it is always interesting to look at the performance of systems on other currency pairs since it brings a hint about the differences between instruments, showing us why a system may work on one and not on another. Understanding and knowing the true nature of these differences allows us to develop systems that are “adapted” to each different currency pair’s trading nature. An analysis of these differences also allows us to change the design of a system- particularly its exit logic- to better exploit inefficiencies found in a particular instrument.

The first think I did with Watukushay FE was to run the “standard” settings derived from very coarse optimizations on the EUR/USD on the GBP/USD, USD/CHF, AUD/USD and USD/CAD (10 year backtests on Metatrader 5). The results are indeed good -as shown in the graphs below- in the sense that the system is profitable in the long term on all of these currency pairs, however it is important to say here that profitability is much lower than on the EUR/USD with most of these pairs reaching only a compounded yearly profit to maximum draw down ratio of 1:3 to 1:5. This shows us that the system tackles a market inefficiency that is present to a certain extent on all these currency pairs but unfavorable conditions are much more frequent than on the EUR/USD.

It is evident when comparing the different equity curves that the smoothest of them is the EUR/USD which – of course – achieves the best results. We see that Watukushay FE has smooth periods of profit on most of these instruments but unprofitable periods are simply very destructive for the other pairs while they are only mild for the EUR/USD. Even tough the equity curves seem to show us that all instruments could be traded profitably the potential reward for instruments other than the EUR/USD is simply not enough to compensate for the risk taken. The deeper draw down periods also make Watukushay FE on other currency pairs far more difficult to trade also limiting risk escalation to a great extent.

However it is clear that some very interesting questions arise. Is it possible to do coarse optimizations on other pairs to find more EUR/USD-like results ? It is possible to implement small modification to the logic that improve the trading technique significantly ? Are there any other instruments worth trading for Watukushay FE besides the EUR/USD ? I will tray to address some of these questions on tomorrow’s post.
