Quote from romik:
...So I decided to to split my trading capital in 2 and dedicate 1/2 to primary trades and another 1/2 to trades trying to catch the big moves in the S&P...
... meeting the great problem when/where to exit, all, or partial, or MOC ?
There are some ressources claiming there is no way with one set of contracts, means all in/all out, below an excerpt from daytradingbulletin claiming a minimum 2, better 3-5 set of contracts is the way to go....
To add my own opinion first: There`s again no easy answer....In testing breakoutsystems i could not found any edge by scaling out or in, under rare conditions adding to winners was the only advance. Different is trading pullbacks in trends, all daily systems I developed working only good cause they scale out from a set of 3. L. Raschke keeps a coreposition in trends and scalps in trenddirection. Scaling out makes only sense if your entrysignal gives you a very high% going at least some ticks the right way immidiately, what I guess is the case with your`s tradingstyle here...By not having this high %, you have no advance cause you get stopped out too often with full position, leading to a negative effect of scaling out. Personally i have great problems with profittaking in discrete trading with a 1 set, cause i have to decide if this is more a trendday or not, and sometimes I end with breakeven, cause too greedy, not seeing the signs... In contratrend Strats I would say all in, all out, only sense making would be scaling in(adding to losers), but in backtesting this ended of course with some rare, but cruel drawdowns.
Here`s the statement from Daytrader`s bulletin:
When to exit a trade is always a difficult question. Longtime professionals incessantly question the ideal exit points for their trades. Part of the answer to the vexing question of exiting is found in how many contracts you trade at entry. If you trade single-lot contracts, you must exit after a certain dollar amount is gained. You cannot allow a retracement (that may turn out to be a market reversal) to rob you of your tenuous gains. When you trade three or more contracts, you can take the dollar gain on the first contract, lower your protective stop to break-even for the second and third contracts, and lock in a winning trade with the potential that the market may run with the remaining contracts. This is an optimal situation. Remember, if you trade one contract lots, you must exit after a certain dollar gain. If you do not, you will be guilty of being greedy, and you will become a market statistic. The Daytraderâs Bulletin assumes you trade a two or three contract set, although you may trade one or more contracts in a set. It is advantageous if you trade a three contract set, four contract set or a five contract set. Above this, you should trade multiples of five contracts in a set. If you use these contract set sizes, you will gain better fills both entering and exiting your trades because these are the lot sizes that are normally traded on the floor.If you trade a one contract set, you must slowly and patiently increase your account size so that you can eventually trade a two contract set.In multiple contract sets your net profit, percent profitable, win/loss ratio, and average winning trade amount all increase substantially compared to single contract sets.
Any more suggestions about exits?
