hi Sanjay/ Karthik,
just for my info:
a) what do u mean by buy /sell trading signal?. do u mean record trade on excel sheet and then post next day close and then it will be reviewed.
b) what abt data of FNO. (most of us use free data thru downloader of Pankaj or srisara).
c) as we use free data(these do sometimes have spikes) which might distort the signal.
pl reply as i am following these posts very keenly, though i am not a active participant.
Presently i am using Soumya's clean database and further appeneded with free NSE data.
The Buy and Sell signals are generated by the various systems we are implementing. The code is attached in posts above, the logic is discussed in Karthik's thread.
To make things simpler in the first implementation exercise we are not using intraday signals. The signals are genrated based on EoD data and the (Mock)trades are to be executed next day in the market at prices available at opening (it may not be the exact open recorded by the exchage, we take actual available price)
All the trades taken this way will be recorded by the trader/implementor (we call him/her Foilio Owner) and every folio owner will make (minimum) one post recording the day's trades (if any) and also the new signals that are genrated, which have to be acted upon next day.
We are leaving the choice of Cash/FnO to the folio owner.
The data has to be maintained by the folio owner at their end.
All the AFLs with the systems and explorations are/will be shared in the forum. Most of them have been programmed by Karthik, and one by Anant.
I agree with you that using free data and trying to maintain it ourself may result in minor distortions.
But with help from people like Soumya who painstakely uploads the data on daily basis. Pankaj and Satya who has given us excellent software to seamlessly update our data, things have become much easier. We can't thank them enough.
Please feel free to ask any further queries you may have, will do my best to answer them
