原帖由 wfy05 于 2005-12-2 08:02 发表 我这里没问题啊, H8的数据多少以及是否完全取决于H4, 差不多是H4的柱条数/2 你转化后看离线历史数据列表里面H4和H8的柱条数量以及时间数据看看.

更新到1.3版本，解决了当重新启动后新加载的数据过多时候可能出现的数据丢失情况, 并且现在支持源数据窗口中新增加了开头的历史数据时候的自动更新. 不过因为现在是周末服务器没有数据刷新没有进行完整测试, 请大家帮忙测试.

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:
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

今晚我比较3分钟和5分钟的K线，发现当某个时间既是3分钟收盘时间也是5分钟收盘时间时，这两个K线图表中显示同一收盘时间的收盘价位却是不同，而且相差较大，比如GPBUSD在2005.12.2 14：45（MT里的时间）3分钟图里显示收盘价为1.7313，在5分钟图里显示收盘价为1.7326，这是怎么回事？盼请高手解析
