Does the market care about your portfolio? If not why would your stop losses be based on your portfolio? That's dumb. Use ATR and set your stop loss
You should think before you post. I certainly do not use ATR for stop placement, but my stop placement is based on technical factors. Risk management rules then decides the size of the position, i.e., how many contracts I can trade and when to stop trading for the day. Other situations that arises can be that the stop needed for a trade is too big for the trade to be justified/allowed. Then, the trade is not taken.
What is this bullshit then: For my account at 15K, this means: a) 225 USD -> 4,5 ES points per 1 contract; 2,25 ES points per 2 contracts b) 600 USD -> 12,00 ES points per 1 contract; 6,00 ES points per 2 contracts c) 1500 USD -> 30,00 ES poinst per 1 contract; 15 ES points per 2 contracts
I did not say those were my rules. They are Monroe Trout's rules and I brought them up here as they're relevant to the subject at hand. On an individual trade level, it means that my maximum risk when risking 1,5% per trade is 4,5 ES points per 1 contract on a 15 K account. If I can use a 2,25 point stop or less; I can use 2 contracts. Day trading ES, my stops range from 1,5 to 3,0 points depending on market volatility and entry, so I'm well covered for 1-2 contracts. If I needed wider stops than 4,5 ES points per contract, I'd need to either allocate more capital, decide to risk more than 1,5 % or find some other money management methodology.
that's not stop loss. Kelly criterion is how much to bet. Your stop loss is where to place your "uncle" price.
And when you know where to place your stop loss - your money management rules/methodology tells you if you have sufficient capital to take the trade and further how many contracts/shares to trade. Not sure what your argument is here.
