It depends. If you would mentally close the position, would you re-open it again at 1.03?
Going from 1.1 to 1.03 is a relatively high loss - Without knowing your strategy it's difficult to say, but I think you should have closed it already.
Having more upside than downside is not the end-all of the game. It also depends on the chances with which that upside is reached. If you view the markets as completely random, these chances diminish the potential for profits. I mean: if you take a profit of 4 ticks, while taking a loss of 2 ticks, that would make you rich if you had a 50% chance of reaching the 4 ticks. Unfortunately, that will not be the case. Realistically, you'll reach those 4 ticks without being stopped out about 2/(4+2) = 33% of the time. This gives you a long term expected profit of 1/3 * 4 - 2/3 * 2 = 0. It therefore boils down to finding market anomalies and exploiting them.
