I develop and test MetaTrader 5 Expert Advisors with a focus on backtesting, forward testing, and risk management.

My products do not rely on martingale, grid, or averaging strategies.

Backtest results are historical test results only and do not guarantee future profits. Please test any EA in the Strategy Tester and on a demo account before live trading.

NINJA Trend Matrix MT5 Pro NINJA Trend Matrix MT5 Pro 将多时间周期市场环境面板与基于已收盘K线的图表分析事件结合。它显示EMA20/50,并提供EMA交叉、EMA回踩和突破前十根已收盘K线区间三种可选模式,以及ADX筛选、分析箭头和虚拟退出标记。虚拟退出不代表真实订单、成交、持仓或交易成绩。本指标不会下单、修改或平仓,也不保证收益。请先在模拟账户图表上检查显示和设置。 EMA20和EMA50线可分别隐藏,颜色和线宽可调整。分析箭头与虚拟退出标记的颜色和大小也可设置,方便与其他指标同时使用。面板有空间时显示模式、ADX阈值及最近的分析事件。箭头所代表的条件只能在该K线收盘后确认;退出标记不是成交价格。

NINJA SYMBOL PASSPORT MT5 PRO NINJA Symbol Passport MT5 Pro是一款只读型MT5工具,帮助您在自行作出交易决定之前,集中查看经纪商提供的交易品种规格和当前执行条件。面板和输入参数名称使用英语。 在SYMBOLS页面中,您可以检查交易时段、到期信息、交易量规则、点差成本、预估保证金、Spread/ATR、Trade Mode、执行与成交模式、允许的订单类型、Stops/Freeze Level、隔夜利息、Tick Value及合约资料等信息。 PREFLIGHT只针对已实现的执行条件进行非方向性评估,包括点差、保证金、报价新鲜度、Trade Mode、交易权限、品种规格和用户设置的风险条件。该分数不是胜率,也不是行情方向预测;其用途是显示当前条件及透明的扣分原因。 在PLAN LAB中,您可以为所选品种手动建立最多6种假设请求:BUY/SELL Market、Stop和Limit,并查看该时点的OrderCheck结果、价格、交易量、保证金、Retcode和经纪商注释。BUY与SELL仅表示假设请求的方向,不是交易信号或投资建议。
