    Ray's Friday morning was marvellous, but his afternoon was awful.

    We first telephoned Dukascopy on Thursday morning, to enquire what exactly was meant by the clause in the contest rules that states:

    In general, manual intervening is not allowed. In exceptional cases, the contestant may use manual trades to close positions, but the ratio of manually closed trades must be less than 10% of the total turnover. Dukascopy reserves the right to require Participant's explanation of any manual intervention with Strategy's operation, and accept or reject such an explanation at its sole discretion.
    We were assured someone would call us back with the answer, but nobody did. That process was repeated on Friday. Getting increasingly desperate I asked that same question on the contest support forum. By the time we received an answer it was already too late for poor old Ray. He suffered 3 losing trades in a row as he was whipsawed to hell and back. The first loss was on a position of a mere £1m, but the second was on £11,209,100 and the third was very confusing! I'll discuss that in a moment, but first I'm regrettably compelled to reveal that Ray is sitting in a dismal 93rd position over the weekend. Our sole consolation is that for the moment at least Ray is still more than one up on WallStreet!

    During the week Dukascopy's normal leverage is 100 to 1, but over the weekend they reduce that to 30 to 1. If you happen to be leveraged to the hilt, as Ray has been for much of the last 3 days, the platform automatically opens a hedging order at 18:00 GMT to reduce your overall exposure to that level whilst the markets are closed. You can see the effect of that in the screenshot below, but a bit later on some strange things started to happen:

    Ray's stop loss on his long position of £7,378,690 was hit at 18:46 GMT. £3,234,180 of that was closed, but then the platform rejected the sell order for the remainder. That means that when the markets open again on Sunday evening (we're in the UK remember) the associated take profit order will still not have been cancelled either.

    It looks like next week could be even more eventful than our first partial week in the September 2010 edition of the Dukascopy JForex automated trading contest has been!

    The second week of the Dukascopy JForex strategy contest is well under way, and Ray our Random Robot has had to endure a variety of trials and tribulations over the past few days. Part of our solution to our weekend problems was to turn poor Ray off for a while!

    1. Before the markets opened on Sunday evening we switched Ray off.

    2. After the opening there was a gap up on Cable, so we manually closed as much of our long position as the JForex platform would allow

    3. We went to bed

    4. We awoke next morning

    5. We manually closed our remaining open positions and restarted Ray.

    Fortunately that gap did close, and eventually Cable continued on down. Shortly after we turned him back on, Ray was sitting comparatively pretty in 19th position in the table:

    Ray's first trade of the week was a long, and eventually his stop was taken out in the evening. Then Ray's MMMM performed it's by now anticipated aberrant arithmetic (AAA for short) and came up the cunning plan of shorting £6,537,320. Apart from a few (relatively minor!) ups and downs Ray carried on serenely through the night, and by this morning he had nudged up to 18th:

    Then disaster struck once more, in the shape of the Fed announcement at 7:15 PM (UK time remember!). The initial spike took out Ray's stop at 1.5899, and he crystallised yet another massive hit to his account. Next he decided to go long the pound, but due to his much diminished assets Dukascopy would only let him buy 4,240,480 of them.

    After some wild gyrations by the markets, Ray indulged in some wild gyrations of his own when finally on of his targets was hit. He celebrated by buying a much more sensible £1m, but is now languishing down in 94th place:

    Note that a new leader from Norway has raced into the lead, with remarkably few trades under his or her belt. ipleX may need to keep looking over their shiny shoulder at the contest rule that states:

    The maximum profit on a single position must be below 50% of the total profit of all positive trades. If not, Dukascopy reserves the right to decrease the total balance of the account for an amount equal to the profit of the position and apply the rule recursively.

    After ascending to the dizzy heights of second place in the Dukascopy JForex September 2010 automated trading contest last week, Ray has been gradually descending into the depths this week. The problems with his Martingale Money Management Module (MMMM for short) haven't gone away, not least because we're not allowed to make any changes to Ray's artificially stupid electronic brain! With his hastily chosen 50/50 TP/SL levels Ray has been getting whipsawed to hell and back throughout the second half of the week:

    He now finds himself languishing all the way down in 114th place over the weekend. Dukascopy's JForex platform has once again hedged Ray's current long position in Cable, and we're going to find ourselves risking disqualification once more when we eventually manually close it.

    Heading into the final week of the contest it would be nice to think that the only way is up from here. After some gyrations of his own ipleX is racing away from the chasing pack in first position. Unfortunately there is still plenty of room below too. The wooden spoon is currently held by an account containing the grand total of -$80.50!

    Midway through the final week of the Dukascopy JForex September 2010 automated trading contest, and Ray's inadvertent overtrading has taken its inevitable toll. ipleX, presumably with the benefit of bug free Java code, is still way out in front hand has turned its starting bank of $100,000 into very nearly a cool $1 million. I can't wait to get my hands on that source code at the end of the contest!

    Ray by way of contrast, thanks to his inadequately converted MQL4 code, has reduced his $100,000 to a mere $13,685, and is now languishing down in 116th position this morning:

    Ray is always an optimist however, and fully expects to perform much better in the imminent October competition, thanks to his freshly conceived, native Java, eternally stupid, metal mind.

    Ray the Random Robot Finishes 117th out of 132

    As the final bell tolled on the September 2010 Dukascopy JForex strategy contest Ray had slipped one more place down the table. After an extremely exciting fortnight battling 131 other competitors and bugs in Dukascopy's MetaTrader 4 to Java conversion software he'd managed to reach 2nd place at one point, but finally finished way down in 117th position.

    Ray had managed to reduce his initial $100,000 in Monopoly money to a mere $8,612 by the end of the competition. The winner did rather better, and almost managed to reach $1 million ($988,696 in fact). The holder of the wooden spoon lost even more than their deposit. Their final total was -$80.50.

    Ray is hoping for much better things next month. His bionic brain has been completely refreshed. It's now full of Java, but unfortunately very little else.
