Why have a stop loss so close to support? I would go at least 10% off that and be buying around the support being confirmed with volume. Today was a good day as a retest confirmed support. However indicators are still down hence dangerous that this could slide. So protection of capital is important. However having stop loss so close to support will result in false break of resistance hitting stop loss. The percentage is upto each individual however if you are too conservative with stop loss with volatile stocks like ton you will end up being struck out frequently in the normal swings. If this is the case go to less volatile stocks like Mgx or org or even aok. Ton can have days where there is sp movement of 6 cents and sometime into Double digits intraday.
