Risk management includes learning to trade well. Learning how to read the charts by doing so means you can calculate whether to go long or short. You will only appear greedy when you don't know when to exit your trade, when you see the chart that the market is almost going to burnout you can calculate and sell and wait again. You will only realize you being greedy when you lose the trade because of greed or simply chasing the pump when its already about to dip.
