//+------------------------------------------------------------------+
void OnStart()
{
//---
MqlRates rates[];
kl.getRates(rates,50);
int f_h;
//1.正常文件写入流程(一般打开这个属性FILE_SHARE_READ，其他进程也可以查看)
f_h=FileOpen("abc.txt",FILE_READ|FILE_WRITE|FILE_TXT|FILE_SHARE_READ,",");
FileWrite(f_h,TimeToString(rates[0].time),DoubleToString(rates[0].open,Digits()));
FileWrite(f_h,TimeToString(rates[1].time),DoubleToString(rates[1].open,Digits()));
//1.2Writes to a disk all data remaining in the input/output file buffer.
FileFlush(f_h);
FileClose(f_h);
//2.文件读取操作
f_h=FileOpen("abc.txt",FILE_READ|FILE_WRITE|FILE_TXT|FILE_SHARE_READ,",");
while(FileIsEnding(f_h)==false)
{
//2.1返回整行的数据（2017.05.03 02:00,1.09307）
string fr=FileReadString(f_h);
}
FileClose(f_h);
//3.在文件底部添加数据，而不是直接覆盖
//3.1推荐用csv格式，不需要有分割号，
f_h=FileOpen("abc.csv",FILE_READ|FILE_WRITE|FILE_CSV|FILE_SHARE_READ);
FileSeek(f_h,0,SEEK_END);
FileWrite(f_h,TimeToString(rates[0].time),DoubleToString(rates[0].open,Digits()));
FileWrite(f_h,TimeToString(rates[1].time),DoubleToString(rates[1].open,Digits()));
FileWrite(f_h,TimeToString(rates[2].time),DoubleToString(rates[2].open,Digits()));
FileFlush(f_h);
FileClose(f_h);
//4.删除文件
// FileDelete("abc.csv");
//5.二进制文件读取操作
f_h=FileOpen("test.bin",FILE_READ|FILE_WRITE|FILE_BIN|FILE_SHARE_READ);
FileWriteDouble(f_h,1.23456);
FileClose(f_h);
f_h=FileOpen("test.bin",FILE_READ|FILE_WRITE|FILE_BIN|FILE_SHARE_READ);
string valueD=FileReadDouble(f_h);
FileClose(f_h);
//6.文件的复制（文件夹和目录）
f_h=FileOpen("directory\\abc.txt",FILE_READ|FILE_WRITE|FILE_TXT|FILE_BIN|FILE_SHARE_READ);
FileWrite(f_h,TimeToString(rates[0].time),DoubleToString(rates[0].open,Digits()));
FileWrite(f_h,TimeToString(rates[1].time),DoubleToString(rates[1].open,Digits()));
FileFlush(f_h);
FileClose(f_h);
FileCopy("directory\\abc.txt",0,"directory\\dcd.txt",FILE_REWRITE);
//6.1文件夹创建
FolderCreate("test");
FolderDelete("test");
FolderClean("test");
//7.文件搜索遍历
string fName;
int s_h=FileFindFirst("directory\\a*.*",fName);
if(s_h!=INVALID_HANDLE)
{
do
{
if(FileIsExist(fName)==true)
{
printf(fName+"这是一个文件");
}
else
{
printf(fName+"这是一个文件夹");
}
}
while(FileFindNext(s_h,fName)==true);
}
}

二.图表操作
1.操作如下图表

2.代码实现

//| Script program start function |
//+------------------------------------------------------------------+
void OnStart()
{
//1.打开制定周期的图表
ChartOpen("GBPUSD",PERIOD_H1);
//2.1获取图表属性ChartGetInteger ChartGetDouble ChartGetString
int cMode=ChartGetInteger(0,CHART_MODE);
if(cMode==CHART_BARS)Alert("柱状图");
if(cMode==CHART_CANDLES)Alert("蜡烛图");
if(cMode==CHART_LINE)Alert("线形图");
//2.1.1获取当前图表价格边界
double min=ChartGetDouble(0,CHART_PRICE_MIN);
double max=ChartGetDouble(0,CHART_PRICE_MAX);
string eaName=ChartGetString(0,CHART_EXPERT_NAME);
string scriptName=ChartGetString(0,CHART_SCRIPT_NAME);
//2.2设置图表属
ChartSetInteger(0,CHART_SHOW_ONE_CLICK,true);
//3.遍历所有窗口，可以关闭指定类型的货币窗口
long first_chartId=ChartFirst();
for(int i=0;i<200;i++)
{
string symbol=ChartSymbol(first_chartId);
//3.1 关闭指定货币的窗口
if(symbol=="EURUSD")
{
ChartClose(first_chartId);
}
first_chartId=ChartNext(first_chartId);
if(first_chartId<0)
{
break;
}
}
//3.1当前宽口价值指标
int ma_h=iMA(Symbol(),0,5,0,0,0);
ChartIndicatorAdd(0,0,ma_h);
int bands=iBands(Symbol(),0,20,0,2.0,PRICE_CLOSE);
ChartIndicatorAdd(0,0,bands);
//3.2遍历指标
int indicatorsTotal=ChartIndicatorsTotal(0,0);
for(int i=indicatorsTotal-1;i>=0;i--)
{
string indicator_name=ChartIndicatorName(0,0,i);
//3.3删除指标
//ChartIndicatorDelete(0,0,indicator_name);
//3.4获得指标句柄
int indicator_h=ChartIndicatorGet(0,0,indicator_name);
}
//4.模板操作
//4.1加载模板
ChartApplyTemplate(0,"ADX");
//4.2保存当前页面为模板
ChartSaveTemplate(0,"testTemplate");
//6.屏幕截图（交易的时候可以截图留底）
ChartScreenShot(0,"1.jpg",800,800);
//7.获取最近操作的错误码
printf(GetLastError());
}
