My Risk Analysis sheet before any trade. First thing I do before trade is determine Max Loss. If Im willing to risk 500$ as my max loss and there is still 0.50 of range till my risk zone, then I only size in accordingly so If it breaks my risk level I only loose 500. Max size and Max risk go hand in hand. Always determine max size based on risk.
In example above I still had 0.40 of range to add the rest of my shares before it hit my risk level.
Absolutely critical to master RISK, MAX SIZE AND MAX LOSS when trading size. If you put on too much size then it hits your risk level the loss can be greater then expected.
