股票买入前决定：1. 卖出价位，2.止损价位，3. 收益和风险比, 4. 持股时间（DT 或ST）。 keeping a trading diary.
指标: moving average, envelopes or channels, support and resistance zone, other methods.
1. moving average: use weekly chart make decision( to predict target price zone, e.g. between two moving averages) and daily chart to exit.
2. chnnels: as price goes up, the moving averae lag behind the price move. This is why moving averages do not make good targets during steady uptrends. 从这点上看，买卖ugaz，jnug, uwt和LABU要用趋势线结合支撑和压力线更有效。此时，moving average帮着确定股票价值，而channel来确定超买和超卖。
a trading system without stops is not a system.
