请教若要在文件开头加上一字符串"date,time,open,high,low,close,volume"
要如何设置，尝试
string strname;
strname="date,time,open,high,low,close,volume";
FileWriteString(CSVHandle, strname, 44);
FileWrite(CSVHandle,
StringConcatenate(TimeDay(i_time),"/",TimeMonth(i_time),"/",TimeYear(i_time)),
//TimeToStr(i_time, TIME_DATE),
TimeToStr(i_time, TIME_MINUTES),
DoubleToStr(d_open, i_digits),
DoubleToStr(d_high, i_digits),
DoubleToStr(d_low, i_digits),
DoubleToStr(d_close, i_digits),
d_volume);
。。。。。。
没有作用，没有将date,time,open,high,low,close,volume写在CSV文件的首行。谢谢！

增加TimeShift参数，可以用来设置转化时候的时间移动偏差, 比如在
H1图标上用24作为倍数，并且将TimeShift设置为6, 则可以获得以服务器
时间每天06:00作为起始时间, 第二天05:59作为结束时间的天图,
比如生成的1月18日天图K线是以1.18 06:00 - 1.19 05:00的小时图数据
综合得到的. 其他的依次类推.
如果想用前一天时间的作为日线起始点则可以相应的把TimeShift设置为负数.
注意的是这里的所有时间都是服务器时间，如果想用本地时间还需计算
服务器与本地时间的时差后获得对应的TimeShift.
另外因为生成的D1为MT4内置时间周期，直接生成D1的历史数据的会将会产生冲突,
生成的数据会被MT4从服务器获取的未进行时间偏移的数据覆盖，所以生成的
时候将自动监测当目标周期为D1的时候，离线图表里面显示的名称为M1441(实际内容
就是生成后偏移过的D1数据, CSV文件名因无冲突问题则不会变化)
当TimeShift为0(默认数)时，工作方式同以前的老版本.

Readme:
I. Features:
This is an improved version of period converter for MT4 based on the
MT4's default period converter by metaquotes.
The default period converter script do not support real-time refreshing,
and consume lots of CPU (50%-9x%) making the whole system slow.
Also, the default one is a script which do not save when you exit MT4,
so you have to apply every converter script again after restarting, quite
annoying.
This one fixed all above problems:
1. Real-time updating or custom interval millisecond level updating.
2. Low CPU cost, average 5%-10% or less.
3. Works as an indicator, so can be saved and reloaded during restart.
4. There is no one converter per chart limitation as it is not script
any more, you can only use one window as source to generate as many
new timeframe chart as possible.
5. Auto updating if there is new history block loaded.
II. How to use:
Copy the mq4 file to your MT4 indicators folder (experts\indicators)
to install it as an indicator, NOT script. then in the custom indicator
list, attach period_converter_opt to the chart you want.
It support 4 parameters:
PeriodMultiplier: new period multiplier factor, default is 2
UpdateInterval: update interval in milliseconds,
zero means update real-time. default is zero.
Enabled: You can disable it without remove it with this option.
Other parameters are comments or for debugging, it is safe to ignore them.
Also Make sure you have Allow Dll imports option checked in common tab or
it won't work
After that, File->Open Offline to open the generated offline data. then
the offline data will be updated automatically.
As long as you keep the source chart open and the converter indicator
running, the generated chart including indicators inside will always
be updated. also you can close the generated chart and open again
later from File->Open Offline without problem.
If you want to quit MT4, you can leave those offline chart as other
normal online charts. when you start MT4 next time, those charts will
also be loaded and updated.
III. Notes:
1. Do NOT uncheck the "offline chart" option in offline chart common properties.
or after MT4 restart, it will treat that chart as online chart and request
the data from server, resulting empty chart window.
2. You can attach more than one converter to same window with different
PeriodMultiplier, e.g: you can attach 3 converter with
PeriodMultiplier = 2, 4, 10 to M1 to generate M2, M4, M10 at the same time.
It is even ok to use the M1 chart to generate Hourly chart like H2, which
only cost a few more CPU resource during initial conversion. but usually
most server don't have much data for those short period. resulting the
generated data isn't long enough for long period. so it is suggested
to use Hourly/Daily charts as source when needed.
3. The real-time updating mode updates quotes as fast as possible, but as
this is done via script, and MT will skip calling start() function when
your PC is busy and lots of quotes income. anyway, this seldom happen,
and you can at least get 10 updates each seconds which is much more
than enough.
4. The offline chart don't have a bid line showing in chart, but all data
in the chart including the indicators is still being updated,
so don't worry. you can show the bid line by unclick the "offline chart"
option in chart properties. but which don't helps much and if you forget
to check "offline chart" option before exit. it will cause errors and
become empty on next startup. you have to close the window and open
again from File->Open offline, which don't worth the trouble.
IV. History:
2006.02.16 1.5 Added TimeShift option, can be used to shift hour timeframe
to generate daily timeframe when your timezone is different
from the server, default is zero.
2005.12.24 1.4 faster to detect if data changed by removing float point
operations, added support to output CSV file in real time.
OutputCSVFile = 0 means no CSV.
OutputCSVFile = 1 means CSV + HST
OutputCSVFile = 2 CSV only, no HST .
(useful if you want to generate CSV for builtin periods)
CSV Filename will be the same as HST file except the extension.
added safe checking for PeriodMultiplier.
2005.12.04 1.3 Fixed missing data when there is large amount of data
loaded in several blocks, and support auto updating
when new history is loaded.
2005.11.29 1.2 Additional fix for missing data and server changing.
2005.11.29 1.1 Fixed missing partial data after restart.
Reinitialize after changing server or data corrupted.
2005.11.28 1.0 Initial release

请教一下wfy05，可以在同一个自定义周期下开多个自定义周期图表吗？
我的意思是，比如我想用240分钟的图表，那我打开一个60Min的图，设置好Period_Converter_Opt，那么在离线数据里面就有了240的图，我可以打开多个240的图，然后分别用不同指标么？比如一个用macd，一个用rsi等。。。
我曾经这么使用过，但是不知道是什么原因，经常自定义周期的图表不自动更新了。。。
非常感谢wfy05，这个东东很实用，再次感谢！
