p*******0 发帖数: 420 | 1 他家api都提供什么?除了股票 option future quote有么?同时可以监视多少只股票?
谢谢 |
n**x 发帖数: 606 | 2 都有,不过只能监控100只股票. 监控时只能得到level 1的数据,没有level 2.也就是
说监控到的数据是每100 millisecond的一个snapshot...对于想做系统的IB的API还是
很有局限性. |
p*******0 发帖数: 420 | 3 可以得到历史数据么?
比如我1分钟扫一次,可以把这一分钟的交易都扫了么? |
c*******y 发帖数: 1630 | 4 there is level 2.
but you are right, no real tick, only 100ms VWAP.

will get pacing violation.

c*******y 发帖数: 1630 | 6 Right, details
Historical data requests are subject to the following limitations:
l Historical data requests can go back one full calendar year.
l Each request is restricted to duration and bar size values that return no
more than 2000 bars (2000 bars per
request).
All of the API technologies support historical data requests. However,
requesting the same historical data in a short
period of time can cause extra load on the backend and subsequently cause
pacing violations. The error code and message
that indicates a pacing violation is:
162 - Historical Market Data Service error message: Historical data request
pacing violation
The following conditions can cause a pacing violation:
l Making identical historical data requests within 15 seconds;
l Making six or more historical data requests for the same Contract,
Exchange and Tick Type within two seconds.
Also, observe the following limitation when requesting historical data:
l Do not make more than 60 historical data requests in any ten-minute period.

c*******y 发帖数: 1630 | 11 OK, I figure it out.
solutions:
1. use orderID of the first order of the group which is unique anyway.
2. use system time
