信号为左侧交易的终点，也是右侧交易的起点，一旦右侧交易形成就是一波主升行情 ，指标包括主图幅图选股指标在内，指标无加密无未来函数，手机通达信可以使用。
1、在股价下跌时，以股价底部为界，凡在“底部”左侧低吸者，属左侧交易，而在见底回升后的追涨，属右侧交易。
2、在下跌中，左侧交易的成本相对较低，距离底部区域较近，安全系数相对高，但也面临越买越套，提前抄底失败的风险；而右侧交易的优点是上涨趋势明显，买进获利概率大，缺点是追高买进介入成本高，买进后，股指往往回落，追涨风险也是很大的。
所以就做了一个左右临界的信号，信号仅供参考，包括主图幅图选股指标在内
另外懂得战法的可以结合下跌三浪或者上升三浪思路可以更好的把握左右临界点
