Hmm, I'm not sure I can pick values a simply as that. You need to consider the reward:risk ratio of the trades involved (the size of the game) as well as the conditions they're in (how far will they run, how close can you get to them etc.) If you're hunting on an open plain, the prey may run a lot further than if you're hunting it in a thicket of trees in the woods, for example.
Following the analogy: When you're hunting big game you use a big game rifle, which of course uses more expensive ammo. When you're hunting small game, you use lighter weaponry. When you want to take out a tank you might use a bazooka. So one must pick the right ammo/weapon depending on the prey you're stalking.
Let's firstly define the weapons based on the cost of the ammo (size of money risked/stop loss):
Handgun = 1% of account
Hunting rifle = 2% of account
Bazooka = 3% of acount
Now lets define the animals based on the reward they will give you when you get them:
Small game: Anything yielding better than 1:1 Reward:Risk up to 2.99:1 (say.)
Medium game: Anything between 3:1 and 5.99:1 Reward risk (say)
Large game: Anything larger than 6:1 (say)
Rules:
1.) You're only allowed to use your handgun for for small game.
2.) You're only allowed to use your Hunting rifle for medium game.
3.) You're only allowed to your your bazooka for Large game.
Note, the values are sucked out of my thumb so you would need to try them and adjust/tweak them as appropriate.
As for actual tick/pip/point distances -- again this will depend on the terrain. If you're in a wood you'll have lots of resistance/support close by. Your targets and stop losses will then be relatively close. In a more open terrain the distances will of neccesity be larger so both your stop distance and targets will likely be larger. But, in all cases the % risked over that distance should be as prescribed for the animal you're hunting, no more.
Hmm, I think we might be reacing the limits of this analogy...
