Quote from slacker:
Index Scalping Client questions:
Several IB front-in clients have a feature that will enter the trade with a Limit order and then 'chase' the bid/ask until the order if filled.
The goal is to improve the fill price compared to always entering the order at the market.
The approaches used to chase the bid/ask include:
1. Place limit order and wait n-number of seconds for a fill. If not filled within that time period, replace the limit order with a market order.
2. Place the limit order and replace the limit price with new price as the market moves away from your target price. After n-number of ticks away from your target price, place a market order, or cancel the order.
For the index scalpers, the following questions:
1. How helpful is this approach to chasing the bid/ask?
2. What other technique can be used to reduce slippage?
3. What is the best 'front end' for scalping? Buttontrader, Ninja, etc., etc...
Any information on the best entry method for scalping would be helpful.
Thank you
