One week period. The UK dogs have had a choppy week. After ending last week on a downward trend, I’m pleased this week has been generally upward. The higher turnover (due to stake increase as discussed last week) hasn’t increased return, which is what I expected from past experience with this strategy. If the current week is similar I may return to the stake level that returned around 0.1% for the previous 2 months.

Here’s the Aus horses. Disappointed to see another error. And this is with the server located in the UK now, so no lag excuse. A back bet was matched and then the tick offset lay was only partially matched. I’ve checked the Gruss log and found no reason for this. The greening appears to have failed, although the Cancel-All trigger, which is the first step of greening, did execute. The result left me exposed to a possible loss of -£8.33. This time the result was profit, +£26.89 . Read on for a more upbeat analysis.

This is the Aus horses minus the error. Now, with a huge increase in turnover (nearly as much in one week as the previous three) the return has maintained a similar level, bringing a proportionally higher P&L result. This is in contrast to the UK dogs where higher stakes seem to reduce return. More of this please.

A three week period. Good return on UK dogs, no big jumps/errors, however tails off towards the end but nothing too worrying. The removal of the Australian wallet happened and I didn’t change anything. This led to a stake increase of around 30%. I’ll monitor performance to see if any notable change occurs.

The Aus horses traded well initially with a steady return. Then at point 340, which is at the base of the sharp incline (£20 in 3 days, nice), the Aus wallet was removed (20th Sept). The stake increased approx 4x and the rapid up trend continued through Friday returning to a more gradual return for Saturday/Sunday.

I wondered if other bots may have stopped after the 20th although I don’t know why. No reference to the wallet is made in the code, so bots wouldn’t have direct data of the change. There would have been an increase in balance and some traders may code to pause after sudden unexpected profits, as this could be an indication of an error. It’s worth remembering that the result of an error, profit or loss, is irrelevant. It’s still an error and needs attention to prevent future losses. If other coders are more attentive, then this may explain why I saw some greater returns, with their bots being brought back online for the weekend.

Who knows? Maybe a coincidence.

Oscar (UK) has had a month of trading without me interfering and has produced another pleasant chart with a nice profit to show (0.11%).

Over the same period, with an equal amount of input from me, Aus Oscar has managed a profit too, 76p. For international visitors, that’s 1.33 Aus dollar, 1.01 US Dollar, 0.91 Euro, 0.0017 Bitcoin, 0.99 Swiss Franc, etc. Still, it’s positive. The large drop was down to two lays going unmatched (Lapsed). However, I smell a technical issue as the race was due off at 08:05 but the bets were settled at 09:05. Usually Aus bets are settled within 5 minutes. Also they are the only Lapsed bets in the last 3 months. Some more digging may find the answer. And a polite email to Betfair.

The UK dogs have produced a lovely chart and there was increased activity. I wondered if the stake size might be a reason for this (thinking it could fall between baiters) but it didn’t produce this picture of beauty when it was last at this level. I will note this current stake and come back to it if things turn bad.

The Aus horses continued their choppy trend, ending positive this week. From around the 130 point I changed the entry settings (as mentioned in the previous post), restricting market participation and liability. The impact of this is inconclusive from the evidence.

Overall a good return, seeing enough profit to more than cover my monthly costs.
