What to do if you cannot sell into strength.

Pat,  I like how you sell into strength to lock in gains.  But what is your advice if the account is small and you do not hold enough shares to sell a portion into strength. For example I bought 20 shares of WDAY today.   When you sell a portion I look at RS and then decide to sell the whole 20 or hold for larger gains.  I have been selling but as the market gets stronger I am flavoring holding and moving up stops.
