Staking

It’s late so I’ll keep it brief. The P&L for the week is good for Aus but flat for UK. As I said I would last week, I’ve now reduced the UK stake to a level similar to what it was mid August, which is when I was seeing good steady returns with little noise on the charts.

So I’ve dropped from 0.016 x bank (1.6%) to 0.007 x bank (0.7%). If I get returns as before I’ll have to make a decision on what to do with the excess bank (only need equiv. 2% stake) –

  1. Leave it where it is, doing nothing.
  2. Create a second Betfair account, for other/future bots or split activities.
  3. Remove from Betfair, put it in savings to be returned to Betfair when required.
  4. Remove from Betfair, spend it (I doubt this will happen).

Any suggestions welcome.

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.

Lost wallet, split history.

As I pointed out in my last post, the Aus wallet has been removed, sent to the cyber dump just behind Woolies. There is obviously a reason for this, by which I mean a cost saving. One slight annoyance is that the Bet History is now mixed up, with Aus bets from before the 20th in “Australian license wallet transactions” and, after, listed under Horse Racing in “Main wallet transactions”. Thanks.

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.

£20 to £300 CHALLENGE!!!

title

I’ve set myself a challenge on the UK greyhounds to get from a starting bank of £20 to £300 in 1 year!

To avoid falling into the trap of setting a challenge and then erasing it from history when it goes pear shaped (like so many others), I kept this beauty quiet for one whole year. I think you can see where I’m going with this. Yes, success (I may have given some clues in my previous posts).

My Oscar has managed to rake in a profit of £286.57 on the UK dogs after commission. Added to the starting bank of £20, I’ve smashed the challenge target, ending with a balance of £306.57, kerching.

1-year

Details if chart is poor –

  • Markets traded = 18,179
  • Settled bets = 136,482
  • Traded volume = £555,831.90
  • P&L = £286.57
  • Return on traded volume = 0.052%

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%).

160904

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.

Aus160731

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

Weeks ending 24-07-16

After a slow start to the period (2 weeks), the UK dogs got into a good trend. The overall positive direction has continued from the restart in late June.

The Aus markets are not doing as well. Looking back over previous charts there is noticeably more variance than on the UK dogs. I am going to respond to this by limiting the parameters before entering market. This will reduce my number of bets but hopefully increase profit (I have done a small amount of back checking to support this).

Some stats

Here are some stats from when I started in September 2015 to now.

Stats July 16

An overall PL/TV of 0.042%.

The number of markets my bot has monitored is probably double the amount it has traded in. Also the number of bets placed will by higher than those settled as I use a fill/kill.

Something else I was thinking about is how Betfair talk about the amount of money they match in events such as the Euros etc. When you place a £10 bet it is recorded as £20 matched, so including the opposite stake. My £600K would be £1,200,000, approximately. But this is done with a bank of a couple of hundred quid. So I wonder how much actual money is used to trade the millions on horses and football every week? Probably only a small proportion of the final “matched” figure.

Week ending 10-07-16

With the UK dogs restricted to higher volume markets, activity remains low compared to previous periods. Both markets ended positive with good ratios.

If trend is kept I’ll step the UK stake up to where it was previously. Currently it is just over £3 where it had been over £7.

The Aus stake has climbed around 30%, due to profit, but still well below the point that caused the turnover charge warning. That was back in February, I’d planned to code around the events where the charge is applicable but haven’t yet.
