接下来的话可能会很扎心，我无意去改变人性，也无意去迎合人性。一个成熟的投资者与新手之间的区别不在于手法、技术，而更多的在于心性和思维方式。一、龙头思维，要做就做第一，喝最烈的酒、干最妖的票、挨最毒的打。韭菜思维是贪便宜的思维方式，很多人喜欢去买超跌或低价股，并不是逻辑上认为他们具备上涨的潜力，仅仅是出于本能，他们本能的认为低位的涨起来更就有空间，很多人都在问哪一个是即将的龙头，很多人认为追涨杀跌是人的天性，猜顶摸底次啊是人的天性。二、龙头思维，抓大放小，专注简单，弱水三千只取一瓢饮，只做属于自己的那部分行情，龙头三分之一的时间都是空仓的，三分之一的时间是试错，赚钱的也就只有三分之一的时间。韭菜思维是什么都想搞，无时无刻都想做，而且定位非常不清晰，一会首板，一会追龙头，空仓这辈子是不可能，怀揣着暴富的梦想但是只有三分钟的的耐心，之所以有这样的表现，是很大程度没有清晰的交易体系，缺乏执行力，任何一个方法如果没有自己深度的思考，没有一番纠结的权衡利弊，没有一番笃定，也咩有一段亲身实践的情感体验，你都不可能持续的做下去，这也就是为什么很多人的方法只属于他自己的原因，因为他已经跟他融为一体了。短线龙头说起来就一个字 ，就是等，说起来简单，做起来很难。等意味着你要洗尽铅华，以为这你要各种权衡利弊，意味着你的定位清晰明确，要做到这些不容易，这是一个需要刻意练习的技能而不是学科，要把这些提升到技能的层次，你才会和你的交易系统融为一体。三、龙头思维要具备强者心态自我突破，百分百自我承担，一个强者要充分认识自己，要知道自己的局限性，不断的突破自我，而盈利不过是你不断突破自我的奖励。而韭菜思维是什么呢，骨子里刻满了输家的基因却不自知，与其说别人误导你，还不如说你渴望被误导，他们渴望别人给他们心理按摩，当他们跟你说，20%的收益你要不要，而你的心里想的是，20%怎么能够，至少得50%。你明明知道一个3000的手机，你要在内存，摄像头。等方面做取舍，可你就是希望售货员跟你说这个手机如何的牛逼，就是你内心深处渴望听到这样的话。四、龙头思维是博弈视角，龙头是走出来的，竞争出来的。也是你试错出来的。韭菜思维是一根筋思维，太多人都在问下一个龙头是谁？ 你如果想知道明天的行情如何，你就确问明天有多少人想买，有多少人想卖，想要进入到这种博弈思维层次，你就假设你自己是一个拥有几亿资金的大佬，哪怕你手里只有几千几万，如果把几亿的资金交给你，你不想控盘也不想成为庄家，但是你又能足够影响价格的走势，你会怎么办？你会考虑到你和其他投资者的利益关系，你会考虑到他们的投资风格，你会去想有赚钱效应的地方，如果没有，我愿意又应该如何去制造这个风口，我又应该如何去制造逻辑利用逻辑，进去之后，我又能保证自己能够全身而退，一旦你把握住这些核心的问题，那么什么明修栈道暗度陈仓围魏救赵这些主力思维不过是非常简单的事情。

什么是降维打击？“降维打击”这个词，应该来自于刘新慈的小说《三体》。里面有个“二向箔”，这个玩意儿可以把所有接触者从三维降维到二维，是高等文明的清理员用来打击太阳系文明的武器，当人类无法适应二维的时候，地球文明的被毁灭也就是必然的了。以最直白的话来形容，降维攻击就是一方利用多维度的新型优势去攻击在这个维度上处于劣势的另一方.。通俗地讲，“降维打击”，就是“高纬度生物”对“低纬度生物”的一种毁灭式打击。三维的人，碾死一只二维世界的蚂蚁是何其容易，因为其水平不在一个层次，思维不在一个层次的战斗。我们生活在三维空间，除了平面以外，还有深度，但是对于蚂蚁来说，蚂蚁只知道前后左右，没有上下，那么它的世界近似是二维的。怎样实现“降维打击”要想实现“降维打击”，主要有两种方法：（1）把对方去掉一个维度，给于对手致命一击黑洞听说过吗，黑洞是将所有的维度塌缩到0维度（一个点）。而二向箔则是将三维塌缩成2维，其实质是破坏了三维空间内所有的物质的分子结构。《三体》中整个太阳系就是毁于一片小小的“二向箔”。（2）占居高维度三维生物就是二维生物的神！升维打击理论是指在同一个领域里面，利用不在同一竞争层面、高于同行业竞争者的技术或模式创新对其进行不对称打击，从而更快地占领市场。实现“升维”打击战略的关键是将高级别的技术和行业标准应用到低级别的行业，例如将军用技术应用到工业领域，将工业技术应用到民用领域等。交易里的升维进化与降维打击在金融交易里，也是可以通过“升维进化”来实现降维打击的。同样也是把高级别的技术或工具应用到低级别的交易市场里。高级别技术的一个现实例子是“人工智能技术在金融交易”的使用，当我们还在通过阅读著名分析师的评论而做交易参考的时候，“高维度”的交易者，已经通过人工智能瞬间掌握了“全数据”，对整个交易市场的心态了如指掌。当我们还在纠结于用一个通过看不懂豆粕的涨跌时，“高纬度”的交易者却已经再通过期权赚钱。

在本文中，我想推荐我的从 MQL4 迁移到 MQL5 的指南版本。1. 图表周期在 MQL5 图表中，周期常数发生了变化，并添加了一些新的时间周期（M2、M3、M4、M6、M10、M12、H2、H3、H6、H8、H12）。要转换 MQL4 时间段，您可以使用以下函数：ENUM_TIMEFRAMES TFMigrate(int tf) { switch(tf) { case 0: return(PERIOD_CURRENT); case 1: return(PERIOD_M1); case 5: return(PERIOD_M5); case 15: return(PERIOD_M15); case 30: return(PERIOD_M30); case 60: return(PERIOD_H1); case 240: return(PERIOD_H4); case 1440: return(PERIOD_D1); case 10080: return(PERIOD_W1); case 43200: return(PERIOD_MN1); case 2: return(PERIOD_M2); case 3: return(PERIOD_M3); case 4: return(PERIOD_M4); case 6: return(PERIOD_M6); case 10: return(PERIOD_M10); case 12: return(PERIOD_M12); case 16385: return(PERIOD_H1); case 16386: return(PERIOD_H2); case 16387: return(PERIOD_H3); case 16388: return(PERIOD_H4); case 16390: return(PERIOD_H6); case 16392: return(PERIOD_H8); case 16396: return(PERIOD_H12); case 16408: return(PERIOD_D1); case 32769: return(PERIOD_W1); case 49153: return(PERIOD_MN1); default: return(PERIOD_CURRENT); } }应该注意的是，在 MQL5 中，图表时间框架常数的数值（从 H1 开始）不等于柱的分钟数（例如，在 MQL5 中，常数 PERIOD_H1 的数值=16385，但在 MQL4 PERIOD_H1 中=60）。如果在 MQL4 程序中使用 MQL4 常量的数值，则在转换为 MQL5 时您应该考虑到这一点。要确定图表指定时间段的分钟数，请将函数PeriodSeconds返回的值除以60。2. 声明内容MQL5 中不存在一些标准 MQL4 常量，因此应声明它们：#define OP_BUY 0 //Buy #define OP_SELL 1 //Sell #define OP_BUYLIMIT 2 //Pending order of BUY LIMIT type #define OP_SELLLIMIT 3 //Pending order of SELL LIMIT type #define OP_BUYSTOP 4 //Pending order of BUY STOP type #define OP_SELLSTOP 5 //Pending order of SELL STOP type //--- #define MODE_OPEN 0 #define MODE_CLOSE 3 #define MODE_VOLUME 4 #define MODE_REAL_VOLUME 5 #define MODE_TRADES 0 #define MODE_HISTORY 1 #define SELECT_BY_POS 0 #define SELECT_BY_TICKET 1 //--- #define DOUBLE_VALUE 0 #define FLOAT_VALUE 1 #define LONG_VALUE INT_VALUE //--- #define CHART_BAR 0 #define CHART_CANDLE 1 //--- #define MODE_ASCEND 0 #define MODE_DESCEND 1 //--- #define MODE_LOW 1 #define MODE_HIGH 2 #define MODE_TIME 5 #define MODE_BID 9 #define MODE_ASK 10 #define MODE_POINT 11 #define MODE_DIGITS 12 #define MODE_SPREAD 13 #define MODE_STOPLEVEL 14 #define MODE_LOTSIZE 15 #define MODE_TICKVALUE 16 #define MODE_TICKSIZE 17 #define MODE_SWAPLONG 18 #define MODE_SWAPSHORT 19 #define MODE_STARTING 20 #define MODE_EXPIRATION 21 #define MODE_TRADEALLOWED 22 #define MODE_MINLOT 23 #define MODE_LOTSTEP 24 #define MODE_MAXLOT 25 #define MODE_SWAPTYPE 26 #define MODE_PROFITCALCMODE 27 #define MODE_MARGINCALCMODE 28 #define MODE_MARGININIT 29 #define MODE_MARGINMAINTENANCE 30 #define MODE_MARGINHEDGED 31 #define MODE_MARGINREQUIRED 32 #define MODE_FREEZELEVEL 33 //--- #define EMPTY -13. 预定义变量MQL4 MQL5Descriptiondouble AskMqlTick last_tick; SymbolInfoTick(_Symbol,last_tick); double Ask=last_tick.ask; AskThe latest known ask price for the current symbol.SymbolInfoTickint Barsint Bars=Bars(_Symbol,_Period);BarsNumber of bars in the current chart.Barsdouble BidMqlTick last_tick; SymbolInfoTick(_Symbol,last_tick); double Bid=last_tick.bid;BidThe latest known bid price of the current symbol.SymbolInfoTickdouble Close[]double Close[]; int count;   // number of elements to copy ArraySetAsSeries(Close,true); CopyClose(_Symbol,_Period,0,count,Close);CloseSeries array that contains close prices for each bar of the current chart.CopyClose, ArraySetAsSeriesint Digitsint Digits=_Digits;DigitsNumber of digits after the decimal point for the current symbol prices._Digitsdouble High[]double High[]; int count;   // number of elements to copy ArraySetAsSeries(High,true); CopyHigh(_Symbol,_Period,0,count,High);HighSeries array that contains the highest prices of each bar of the current chart.CopyHigh, ArraySetAsSeriesdouble Low[]double Low[]; int count;   // number of elements to copy ArraySetAsSeries(Low,true); CopyLow(_Symbol,_Period,0,count,Low);LowSeries array that contains the lowest prices of each bar of the current chart.CopyLow, ArraySetAsSeriesdouble Open[]double Open[]; int count;   // number of elements to copy ArraySetAsSeries(Open,true); CopyOpen(_Symbol,_Period,0,count,Open);OpenSeries array that contains open prices of each bar of the current chart.CopyOpen, ArraySetAsSeriesdouble Pointdouble Point=_Point;PointThe current symbol point value in the quote currency._Pointdatetime Time[]datetime Time[]; int count;   // number of elements to copy ArraySetAsSeries(Time,true); CopyTime(_Symbol,_Period,0,count,Time);TimeSeries array that contains open time of each bar of the current chart.

MT5与MT4到底哪个好用？MT5比MT4强在哪里？阿右来告诉你。一、技术上，MT5同样的服务器硬件资源，可以支持更多的用户同时在线和并发，而且有十倍以上的性能提升，但个人觉得这些和用户关系不大，或者和最终买单的交易商客户也关系不大，因此MT5的用户包是用来单独销售的，也就意味着，这些性能的提升主要不是给交易商客户带来多少成本降低，而是给迈达克自身带来了更多的成本优势。二、MT5对接口的支持非常丰富，可以提供移动端，网页端等各种应用程序的再次开发拓展需求，同时MT5的技术文档等支持也做的更为专业、规范。对开发人员来说，选择MT5会比MT4有优势的多。三、MT5自身就设计了Gateway模块，用于对接外部的交易所和流动性提供商。也就是说买了MT5的交易商，可以不用购买外部的Bridge了，直接拿MT5的gateway就可以对接更多的流动性提供商，但还是和第一个问题一样，GateWay是需要单独收费的。MT5的历史回测功能比MT4功能更加强大，可调控性更强。一、在MT5模式下的策略测试，是一个独立于编程块、交易块的一个单独模块，重视程度显著提高。二、从我们在本地下单，到服务器接收到下单指令，是有一个网络延迟的，这个在你MT4右下角服务器那里可以查看。为了能够完全检验策略在一定延迟环境下的表现，MT5提供了可以自设延时毫秒的功能，以及在不稳定网络环境下的随机延时，这样对策略逻辑的检验就很有效了，也减少了回测和实盘交易的误差。三、MT5历史回测时可选择浮动点差来进行测试，完全符合每次报价的实时点差。而MT4历史回测时只能选择固定点差来进行测试，相对而言并没有那么人性化。四、MT5可以支持多线程优化测试，可以调用局域网内的闲置电脑，或者网络上的电脑（付费）来做策略测试，极大的提高了效率。五、MT5支持多货币对历史测试，这样的话，在MT5上可以研发多货币对冲模型，并检验其效果，MT4是不支持多货币策略回测的。

亲爱的各位老板，首先，这个策略很简单，但不是一个圣杯。策略设置使用布林带（周期 20，偏差 2，移位 0）和随机指标 (14,3,3) 的默认值。很长一段时间我第一次学习外汇时，我非常讨厌随机指标，因为我对这个指标的误解。后来我在自我实验后发现了它（当然还有一些我的理念...... ），这个指标可以帮助我：过滤我的情绪（当我必须开仓或建仓时）过滤我的贪心（想短时间内赚大钱）知道我什么时候可以为我的下一个位置做准备（当然有布林带帮助和K线图反转模式）好的，这是我的简单策略（并且我正在使用此策略基础进行 EA 的开发）。*------- 与上波段交叉（对下波段做同样的操作）买入入场1. 前一根蜡烛（来自当前蜡烛）从下方穿过 BB 上线2. 主随机指标高于信号随机指标3. 当前蜡烛看涨和随机指标低于 80卖出入场1. 前一根蜡烛（来自当前蜡烛）从上方穿过 BB 上方。2. 主要随机指标低于信号随机指标3. 当前蜡烛看跌，随机指标高于 20 止盈：50追踪止损 15止损：50时间框架 H1任何货币。我经常使用的K线图 看涨和看跌吞没。请注意外汇是一项高风险的业务，此策略对我有用，因此风险由您自己承担。no.1 没有入口。(随机指标已经超买区域)no.2卖出入场No.3卖出入场 

大家好，我只是想开始一个线程分享迄今为止最成功的外汇交易方法！就这样……很简单。在 1 小时图上，绘制 5/12 EMA。绘制 RSI 设置为 21。当 5/12 向上交叉且 21 RSI 超过 50 时，您将做多。当 5/12 向下交叉并且 21 RSI 低于 50 时，您做空。这种方法被证明至少有 85% 的准确率！我希望这能帮助你们成为更成功的交易者！！！
