Quote from JB3:
Care to explain what exactly are you looking for in the T&S, and share some stories or tips on why the specialist system added to your profitability? Thanks in advance.
Most of this is outdated and of little use now, but in time and sales window I look for last price, last trade size and exchange, I used to have a separate small window with last nyse trade price and size. This together with new york best bid/offer price and size and the nyse open book (during the first years when it just came out, not now) used to give me very good picture regarding the stock I'm trading.
For daytrading the volatile NYSE stocks during 2000-2005 being able to get into and out of positions at reasonable prices was as important if not more important than correctly predicting the future short term moves for the stock. To do this you had to be a couple of steps ahead of the other traders with your orders and anticipate specialist's actions and prints before they happen. It's a little complicated to explain for me, but basically you didn't want to place any market orders with specialist after important levels were broken, and were rewarded with price improvements for your correctly placed limit order if traded "with" the specialist. Big intraday gaps and price slippage/improvements were very common for volatile stocks.
In today's market all the common 1 - 1 bid offer, last trade size don't tell me much.
Currently I'm trading 2 setups. If I'm trading a big gap up I hope it to come down a little bit right after the open on low volume and buy a few shares, and have the stock go back up and brake the high, I'll try to add some more to my longs and exit them for profit after big volume shows in prints on the way up, or if stock starts going down, for a loss if the low of the openning range is broken.
If a stock gaps up and goes higher right from the open I will look for some big volume prints and try to short there with a small stop loss, and hope the stock goes down from there, hold it for a big profit or a small loss.
Same 2 things but in reversal for stocks that gap down.
Like I said the nyse bid/offer size, last trade prints, the speed with which the specialist filled my orders all used to give me good indications regarding the short term moves in the stock, now I'm looking more at overall market conditions and stock sector and longer trades with not as precise exits as I used to have before.
Don't hesitate to ask about anything, I'll try to answer as best as I can, I love talking about anything related to trading.
