To avoid whipsaw losses, stop trading.
In order of importance to me are: 1) the long term trend, 2) the current chart pattern, and 3)picking a good spot to buy or sell.
If you can't take a small loss, sooner or later you will take the mother of all losses.
Longevity is the key to success.
The key to long-term survival and prosperity has a lot to do with the money management techniques incorporated into the technical system.
Risk no more that you can afford to lose, and also risk enough so that a win is meaningful.
