New strategy

With the start of the jumps season just around the corner, I’m going to be pursuing a new, automated, in-play strategy. I did all the hard work last year qualifying what I wanted to do and test the assumptions, which are often wrong. So now it’s time to put it into practice.

It will lose money and on a frequent basis and sometimes for a long run of races. But the whole idea is for it to profit in the long term. Most strategies you see will not do this, especially if somebody is going to try and sell you on something.

Most strategies

If you look at any ebook or system sellers nearly all of them focus on high probability trades, positions that win very frequently. That’s great (for them) because it makes the person who just shelled out some cash feel really good. They keep winning on a regular basis and in an excited hubris they often credit the author with some positive feedback, then booooooom; It all goes wrong. Eventually, reality dawns that it just doesn’t work. The betting and financial industry are awash with this sort of ‘advice’.

Expectancy

To understand your what your real objective is when trading, let us assume we are betting on a coin toss. With a 50/50 chance we won’t make any money in the long term, but we may go on some nice winning runs. If we want to make money we have to up the strike rate or reduce losses, easier than it sounds, but possible.

Whatever strike rate, you look at the equation in basically the same way. If you participate at random in the long term you can’t make any money if the market is efficient, which it is! So you have to increase your strike rate or reduce your losses when you make them. Not by hedging, because you shift the exposure to lose to another scenario, but by finding a way to reduce your loss inside the way the market functions. I’ll have to explain the significance of that sentence at some point!

High probability trading is actually very easy. You can pretty much custom make a strike rate in any sports. It’s impossible to get 100%, but you can go all the way up to 99.9%. If you ask me on a horse racing market, I can deliver a stragtegy that will deliver pretty much any number you want up to that limit. But the problem is, it still wont make money without modification of some of the elements. Better entry, better exit etc. etc.

Why won’t a high strike rate make money on its own? Because if you make £1.00 profit 99 times but lose £100 on the 100th go, you will still be net negative overall. The detailed maths is complicated, but you could actually get away with it and go on incredible winning runs, but eventually your luck will run out. But that’s why people like high probability trading and why people push them, they look and feel really nice.

Where value lurks

The major problem that you see when analysing data from many markets, is that the high probability end of the market is where the least value seems to exists. It is saturated with people trying to wing it, hoping that it’s somebody else that takes the eventual hit. That pretty much destroys all chances of getting a profit. In fact, if often tips it the other way. So the moral of this story is….

It’s actually at the other end of the scale, the “low strike rate, big occasional win” where the value is more abundant. Unfortunately very few people have the mindset or mettle to recommend or pursue a low probability strategy. That probably also explains why there is value hiding away in that little niche. It’s painful to recommend or execute. You look like a fool most of the time and a win can seem lucky or fluky. Worse than that, people will goad you with the losing runs as ‘proof’ that you don’t know what you are doing. It’s enough to put off all but the biggest die hards in the game.

Summary

At the end of the day if you recommend a strategy that loses frequently then you look a fool and people will complain, very few will see it through to the eventual pay off. But if you pursue a high probability strategy then you look like a god because the pay off is frequent in the short term. But even if it is negative in the long term, you can always blame ‘luck’.

When it comes to being profitable, luck just doesn’t enter the equation.

I left a good job in the consumer technology industry to go a trade on Betfair for a living way back in June 2000. I've been here ever since pushing very boundaries of what's possible on betting exchanges and loved every minute of it.

    Hi Peter,

    I completely agree with you. Market is very good at pricing low probability outcomes but high probability outcomes are usually priced based on the book balance. Unexpected events are called unexpected out of ignorance.

    I looked at your strategy with swinging pl. I am a trader and trade derivates. In my backtests when I encounter such an equity curve I usually tend to trade the X day running sum(in your case maybe long and short positions are adjusted based on the derivate of the trendline) so that I end up with something stationary to trade.

    I really like your content and please keep on posting videos and posts.

    Regards
    Yigit
