A respected method is betting 1/200th of current bank , adjusted up or down daily. (Not after each race.)

Doing it this way does not have the massive swings up & down as say betting 1/20th of bank up & down after each race.

The 1/200th approach also allows the punter to breath a lot easier because they already know in advance what they will be doing, if a horror day should strike.

It also allows for all bets to be made at once.

-------------------------------------------------

Another approach is to work out what ones worst run of outs may be
e.g. 20 outs in a row.

Then multiply that figure x 10
e.g. 20 out x 10 = 200 unit bank needed for level stakes betting.
On a bad run , we stand to lose approx only 10% of bank.


An alternative would be ones largest draw down amount x 10
e.g. max draw down -18 units.
18 x 10 = Bank needed 180 units.

That way , the worst case scenario is that we will blow only 10% of our bank.
Most punters can live with that.
