Yes, it is true. when you want a bigger profit, then the risk is also great. we better take a little profit but the profit is stable as we expect. rather than expecting big profits, but eventually things are not as expected and you fail. then you will lose time and also capital. I think the right thing to avoid the big risk is to do daily trading. with daily trading you can take a little profit every day. by always observing the state of the market.
