These components have allowed me to survive:
A Plan - I use three R's here. Realistic, rock solid and respected. This plan encompasses the areas of:
Trading stable - The stocks and ETFs I focus on. I don't care about or trade anything outside of it. I do add, but add slowly and only after I have paper traded the stock and feel comfortable with it. When I trade a newly added stock I use only 25% of my normal exposure, and then increase as I gain more experience with it.
Exposure per trade - Having fixed lot sizes or percentage of capital. I use a scale, "x" amount of shares for risk/reward ratios of "x". When the r/r ratios are higher I increase the exposure, and decrease the exposure with lower r/r ratios or questionable plays.
Strategy - After daytrading exclusively for 7 years with never holding overnights, I began swing trading 2 years ago. This was a very challenging time. I revamped my entire plan and reassessed my strategies. It's amazing how conformity with one timeframe serves as a handicap for another, initially. Later I found that the two schools of thought complimented each other. Having several strategies is great, however the real challenge is having the discipline to use a strategy at the right time. Multiple strategies in multiple timeframes allows you to take advantage of more opportunities. Without discipline, more opportunities means more trouble.
Resource requirements - from the quote platform and OES right down to the Post-It notes, I keep track of everything I need (cost, reason, and status). I use MSFT Outlook calendar to remind me of when I need to have maintanence and upgrades done. When one of these requirements needs to be changed I do it, It doesen't matter if its the B/D I use or a hard drive.
Meetings - No not with anyone else, with myself. Once a month I assemble a presentation, as if I were a CEO making a presentation to shareholders. It may sound a little off the wall, but I found so many faults and open issues that needed to be resolved in the process. I then go to a quite place two days later, a distance from home and review the plan, its a real eye opener.
Journal - its entries are only valuable when they are honest and reviewed regularly.
Last, the ability to change. The environment is always changing, and adapting to the change permits survival.
