RTD ( Open source ) is based on two applications. Backfill - A basic backfill tool to import VWAP statistics / Nest Plus Data table ( Open source ) by Josh1 (TraderJi.com) and RTDman- C++ RTD client for Nest/NOW which Feeds real time data to Amibroker (Open source ) by TraceBullet (TraderJi.com) Special thanks shankar4kv (TraderJi.com) for taking his time and effort to put together this tool and implementing feedback and suggestion. Thanks also to SR114, Shirajroz, Raghuveer, L.V. Gandhi, SmartTrade, rMike, Einstein,snakehead and all other members who have contributed in different ways for development of these applications. Both the applications are open source licensed under GPL2. Links for the source code are given by Shankar. Source code of RTDMan is given in the zip file. Users are free to modify the source code at their discretion. RTDMan gives Real Time quotes in Ami from the time you click on- Start. It does not give Real time from beginning of the day. So start RT and then backfill from either Vwap/Hourly Statistics or from NestPlus. Copy data upto the time you logged in into Backfill. Please note: - Real time data and backfill depend totally upon your terminal and broker. Default number of scrips is 55 for Nest /Now. You may request your broker for additional scrips. Some brokers may give RTD for 100 to 200 scrips. Backfill is done from either Vwap/Hourly Statistics or Data Table. Hence number of days available there is the limit. In most cases Data Table has up to 22 days of 1 min.data. Backfill is available in 1 min. time frame only. In addition to that, you may use ‘Data Downloader’ by Joydeep for backfill of cash scrips from Google.
