Slowest Broker Platform

Guys,

Need 2 Infos:

1. In case you have trading accounts with multiple brokerage houses or trading platforms - which is the slowest or showing Lag even say by 1-2 secs on the ticks comparted to others.
   
2. Is there any brokerage houses in India which allows overnight SL, regardless market gaping up or down (Like guranteed SL of 20 pip based on your previous days SL at market close)?

Thanks.
