Thanks for pointing out to traderji ad..
About your query on order should be rejected by the platform if it exceed the maximum size, this issue is already fixed.. If you place an order more than 10000 for nifty today, the trading platform itself rejects it rather than NSE rejecting it..
Saving Rs 10000 in one order, what I was referring to was, suppose you are buying nifty futures and you want to buy 200 lots at one go..
You can either place limit or market.. If you place limit 10000 qty will show in market dept window and your order might take forever to execute.. Suppose you put market order to buy 10000, if you do this during the illiquid part of the market, during midday or something, you can loose 1point just in impact cost.. So if market is 6010, your market order might get avg bought at 6011.. So on 10000 qty, you loose Rs 10000 only in impact cost.. Imagine if you had to execute such an order on stock futures or options, think about the impact cost!!
We are coming out with order based execution algos that can reduce the impact cost significantly.. 13 algos in all, one such algo which would help for a situation like above would be: iceberg, you can google for what an iceberg does
This product is meant for higher volume traders and will come with additional cost and clauses.. But the idea is to give this tool which institutional traders usually get at a fraction of cost to retail traders in India.
Will update all of you as and when we have the product details ready..
