CAUTION - BACKTESTING, REQUIRED EQUITY and MARGIN-CALL -O- METER.
Zulutrade is an excellent innovative trading platform, but I would just like to inform and caution all my Zulutrading peers about some of the very expensive lessons that I have learned through the unnecessary loss of capital due to misrepresentation of historic data on the Zulutrade platform.
THE BACKTEST
-
Please take note that the backtest is only useful to determine the estimated profit that could have materialised in the past, with the maximum open trades and maximum open lots followed by the Signal Provider, without taking into account any stop losses or stop limits.
-
The backtest does not take your own maximum open trade settings, maximum open lot settings and stop losses or stop limits into consideration. When you change these settings, the backtest remains the same. The only factor which influences the backtest graph is your own ‘lots multiplier’ setting.
-
Do not, however, measure the Max DD on the DD graph and adjust your lot multiplier accordingly, as you will receive a Margin Call sooner than expected. The real DD is, in some cases, up to 10 times more than the Max DD displayed on the backtest graph.
-
The drawdown graph on the backtest only displays the max DD of a trade on the day that the trade closed, not on the day that it happened. It is totally skewed. You can do your own comparison by comparing a SP’s backtest with the SP’s drawdown graph on the SP performance page.
MINIMUM REQUIRED EQUITY
-
The NFA helped traders a great deal by requiring that Zulutrade state the minimum required equity for each signal provider and that they provide a more realistic performance graph.
-
I finally got the formula for your ‘minimum required equity’ from Rose, after numerous attempts. To all my requests I have received various answers – from no answer in the forum, to that it is an algorithm not available to us from the support staff.
She wrote the following:
“The minimum required equity is calculated based on the assumption that you will receive all trades executed by this Signal Provider, and withstand any drawdown that has occurred during his trading activity without receiving a margin call, assuming that you are trading 1 micro lot for each of his trades, with 100:1 leverage.”
For the first time in months I could calculate the Max DD in currency by inversing this formula:
MaxDD($) = Min Required Equity – max open trades x $10
Now I can do my own calculations according to my own leverage and the risk I am prepared to take. My leverage is 200:1 so I multiply by $5 instead of $10. (I am still a little concerned about the accuracy of the ‘minimum required equity’ when it comes to a SP with multiple pairs and SP’s with low percentage winning trades. I have, however, tested and confirmed the accuracy with single pairs.) -
Note that the required equity value changes as you change the time period, for example from ‘all’ to 6 months history, so you can make your own decision on what historical timeframe you would like to base your risk.
MARGIN CALL -O- METER
-
The margin meter has some benefits, but could also be a bit deceiving in some cases. The margin meter reading is determined by the calculation of the worst case scenario by multiplying the worst trades with the max open trades and possibly a few other parameters.
-
The problem is that many SP’s started over a year ago with some bad trades, but noticeably improved their strategy during the last 6 months. Their first few trades will always influence the margin meter reading and it will read a lot more that it needs to be.
-
On the other hand, if you use a SP with a low winning percentage and a low DD you will get a very low margin meter reading. The problem with this is that you could easily lose all your capital – not due to a DD but due to a string of losing trades before the winning trades start! This also applies to the minimum required equity. (In this case it could be best to do a backtest and measure the worst dip in the graph and add the max DD to determine if you have sufficient equity.)
A FEW TIPS ON PROTECTING YOUR CAPITAL
-
The biggest challenge we have with Zulutrade is that any SP could change his trading behaviour in an instant and destroy your account. The auto trading system keeps on auto trading until you run out of money and there is no programmable stop!! I suggested a programmable stop on various occasions to Zulutrade on the forums etc., but doesn’t seem as if that is going to happen.
-
One SP can easily destroy an account with 5 other excellent SP’s. The best solution that I have found thus far, that works with great success, is to open multiple accounts with one SP on each account. For instance, if you have 5 accounts with the same balance with 5 different SP’s loaded and one changes his trading behaviour, you only lose 20% of your capital at most. (One problem is that AAAFx only allows us 2 accounts, but SunbirdFX, with the lowest slippage and the lowest costs, allows unlimited accounts. For personal service and benefits for Zulutrader’s , ask for Michelle)

Using Zulutrade could be very profitable, but we need to challenge Zulutrade all the time to improve the essential information on the platform, that we base our decisions upon, instead of improving the marketing bells and whistles.
