For fun I just back tested one of my strategies from 1981 until today with simple re-investment of profits turned on and it produced a profit of £7.156 million – and it got me thinking – if only I’d known that in 1981. Then I got to thinking about 1981 and how I was 12 years old. State of the art technology was a thing called a video recorder with piano like keys on the front that most adults could not work out how to set the timer on and the only communication our house had with the outside world was a telephone on a table under the stairs with a dial on the front that you had to put your finger in a hole and rotate to dial a number. When we are testing on such old data we need to keep this sort of thing in mind and we also have to wonder what the future data will look like if our technology has developed so far so fast.

Still we can all dream – hopefully after so many years on the market the recent draw down of £3.914 million would not make us sweat too much!
A drawdown of £3.914 million is more than half of the years needed to make that profit! I’d sweat for sure…
I’d sweat for sure…
I think I’d be sweating when I found out that I had a position size of over £4000. You would not want your strategy accidentally stopping and the trade closing out at that point!
It took 32 years to get the first million and at that point it was earning somewhere around £500K a year so I guess we might have gone to level stakes at that point and avoided the £9 million draw down!
Much more sensible. Level stake of 1. No more money management heart attack after 30 odd years. A much smaller house and boat and car though. Maybe just a car.
