I add to losers under the following conditions:
i) If I was flat, I would want to enter at the current price with a larger than normal position (which requires the market to be offering an unusually favourable trading opportunity)
ii) Adding to the loser will not increase my position size beyond my risk limits
iii) I am sure that my judgement is not affected by having suffered an initial loss
iv) I don't think I can exit and then re-enter at a better price
It is quite rare for all these criteria to be met. When they are, usually it is a relatively small loser on a slightly premature entry, which has now started to bounce back.

. As always, choose what works in your system and Test under all possible conditions. You decide because you live the the consequences.
