which online broker provides maximum exposure?

Hi all,
Guys as we must be using different brokers, can we share the type of exposure given by different brokers. I want to reach a conclusion which online broker provides maximum exposure both in cash and derivatives segment. i am using kotak who have divided securities and futures into group A,B,C,D,E for which they provide multiples of 5,4,3,2,1 respectively.
For eg SAIL is placed in Group A it means you get a multiple of 5 i.e. you pay 20% margin for a lot of SAIL, and RNRL is placed in cat D it means you get a multiple of 2 ie. you pay 50%. for nifty futures they provide multiple of 10. this is not intraday. for intraday they have a group of 15-20 scrips for which they provide a multiple of 8 it means you pay in multiple of 8 ie. you pay a margin of 13-14% but they will square off your positions at 2.30 pm if you do not square off before that.
my basic purpose of this querry is to find out which broker provides maximum exposures in futures segment irrespective of intraday, i mean you can hold that lot untill expiry. so who offers the best exposure for futures so that you can hold it untill expiry.
thank you all in advance

anagram offers 20 times exposure.

high margin = high risk = high reward

5paise gives 6-8 times in A group intraday. for FnO their span margins are avaliabl hee http://www.5paisa.com/5pit/spma.asp

for nity its 36224 rs. in general they are conservative

i heard PIB gives more. most bokers wont give much exposre in FnO as u can carry over subject to M2M.

you are right.But though Anagram offeres high leverage,it squares off your trade if loss in your nifty position(20 times levrage is meant for nifty only) touches 80 points.It amounts to 80*50=Rs.4,000.If your brokerage house asks for conservative margin as prescribed by NSE,than also amount of loss will be same.I have heard that many brokers/sub brokers offer more attractive leverage than Anagram to increase their brokerage earning.But you should control your greed.DO NOT INDULGE IN OVERTRADING.I do not have any vested interest in this brokerage house.
