Most investors and many more market pundits continually talk about setting stops; they range from physical stops to mental stops to trailing stops to support stops to retracement stops or even moving average stops. It is easy to set a stop before you enter a position based off of your money management rules such as position sizing and expectancy. If you have a $25,000 account and want to risk 2% of the account on a $50 stock with an 8% stop; we know that the trade will allow you to buy 125 shares with a worst case scenario sell stop of $46.00 (assuming a 1-R risk of $4). This is wonderful but what should a trader do once the position gains 20%? Where should the stop be placed at that point to eliminate the chance of losing that quick 20% gain?

Several books attempt to explain how to take profits and many traders of the past have offered advice in books but most of it is fluff and subjective to opinion. I have heard people claim that they take a third of the position down after making a 20% or 30% gain while other traders take down half the position once a gain reaches 50%; but is this the correct way to manage money and positions? I thought so several years ago but have developed a more mechanical system that gives me precise exits at any time during an up-trend. It is a combination of a trailing stop and a retracement stop based upon the actual gain at any point in time. In a bull market, I will allow the system to loosen itself so I can handle a healthy pull-back without selling before a possible large move. For now, let me focus on my method for locking in profits without giving back too much.

For the sake of this article, I will continue to use the trade suggested above as the round numbers should be easy to follow.

Account Size: $25,000

Risk: 2%

Stop Loss: 8%

Share Price: $50

Shares to Purchase: 125 or $6,250

Sell Stop: $46.00

Worst case loss: $500 or 2%

If you are unsure how I came up with the numbers in this example, please go back and read my article on position sizing.

We buy the stock and it is up over 20% after the first three weeks of trading. What should I do to protect the profit I have already made?

Scenario #1: At $60, I will set a stop based on a 30% profit retracement.

To do this, you need to multiply the profit of 20% (or $10) by a 30% stop: $10*30% = $3

At this point in time, I will look to close the position and lock in gains if the stock drops more than $3 from the $20% threshold ($60 in this case). My trailing stop is now $57 which guarantees me a total gain of 14%.

Scenario #2: At $65, I will set a stop based on a 25% profit retracement. As my profit grows, my stop tightens so I don
