This is the nuts and bolts of trading at its finest...trade management...I do not think that there are any "hard and fast" answers to this question...Without a doubt, this is the aspect of trading the gives one the most creative freedom within certain limits...
Depending on your capitalization, there are many ways to either average your cost and/or average your exits, etc...Mainly, the most important part of the plan is the planning stage...For instance, I think one of the most important things to consider at all times is a) your basis cost and b) the success of your entry...You have to be very objective about the latter...Sometimes if you enter following a breakout and you have to much size on, you take the risk of trading into a "hole" and then you have to ask yourself, is this trade worth the risk of letting the market run me over as it runs back to the breakout point...If you are fairly certain you have nailed the short term high or low, then you may have a bit more latitude as far as exits go...
I think alot of traders take unnecessary losses at certain times that could be managed better if they could objectively assess the success/failure of their entries...Without a very good entry, the trade basically becomes about playing defense really quickly...With a good entry, the trade becomes about managing the profits...Sometimes, if trading in a range and the first entry is not perfect, but the trade is still inside the range and the market still suggests the original direction, adding to the trade is a viable option as well...
As far as adding to a position as it proves you right, ...You have to decrease your exposure as the trade moves your way...but again, this relates to your basis cost...How much of a profit do you have and how will the add-on affect the overall profitability of the trade...
Actually, there was a typo...I did not intend to say decrease your size, per se, but rather decrease the add-on contract size relative to your initial entry...For instance, if 10 contracts on the first entry, perhaps 3-5 on the add-on entry...This way you do not jeopordize your entire cost on the trade should the market come off and retrace a bit back towards the entry...
