趋势跟随类 EA源码分享:纯趋势逻辑,无加仓无马丁,布林轨道拐点识别 + 一次一单 + 动态追踪止盈 的趋势跟随 EA!HI，大家好，周末EA分享日！ 今天带来的是一款老版本的MT4的EA,基于 3 根 K 线的布林带轨道形变判断趋势拐点，搭配动态追踪止盈（移动止盈），单 K 线仅允许开一单，属于趋势跟随类 EA。
2. 开仓规则
- 单根 K 线只开一次仓
： if (Time[0] != OrderTime) OrderOpen = false;防止同一根 K 线反复重入、重复加仓； 持仓状态标记 OrderOpen，有持仓时不再触发新单，是一次一单 EA，不带马丁、不带加仓；可配置参数：手数 Lots、滑点Slippage、魔术号MagicNumber；开仓仅设置滑点，开仓时不预埋固定止损 / 止盈，盈亏控制靠后端动态移动止盈和条件平仓。
