In fact, pair trading works well with positionals and gives good returns. You can even buy both the securities at the next day's open price (
@ncube may throw more light on it). I am a bit hesitant to advise on this since I haven't live traded on them so far.
For it to work intraday, you must update data more regularly for all parameters (look back period, buy and sell price, z-score threshold)
@VJAY,
For positional I dont force trade, so I keep limit orders the previous night around the close price of the stocks. Most often based on my experience atleast 1 of the stocks will get executed at the limit price in the morning, once a trade is executed I will convert the 2nd trade to SL-M at the low of the 1min candle pivot. If the price does not hit I will wait till the 3:15 and execute it at market price so that the pairs are hedged before market closes.
However If you want to ensure the trades are always executed you can follow this approach and it can also be used for day trading:
Wait for the 1st pivot to be formed on a 1min candle and place SL-M/Limit order above/below the pivots for the stocks in the identified directions.
Another method which works for day trading and you guys can explore:
In pair trading Y stock direction is the prominent direction in which the stocks would most likely move, hence one can use the Bracket Order (BO) to make quick profits as follows:
Direction to trade: Y-Stock Direction as per pair analysis
Trading rules: Use 1min candle pivot breakout or 15min candle breakout for both stocks in the same direction as Y-stock
Profit & SL target: About 0.03% of the stock price.
For example: If the Zscore is -2.5, which means as per our pair analysis the Y stock need to be bought and X to be sold. But in this we will not short X, rather we will buy as we want to trade in the prominent direction of Y and it will be a quick short term trade.
Say Y stock price = 300 & X Stock price = 500
Now wait for the 1st 1 min candle pivot or 1st 15 min candle to be formed.
Place SL Buy BO at the top of the pivot or 15 min candles for both the stocks with SL & Profit target which is equal to 0.03% of the stock prices. i.e Ystock = 300 * 0.03 = 0.90 paise & Xstock = 500*0.03 = 1.5 rs.
There are many ways one can use pairs logic and execute trades, hence I suggest one can explore the method one is comfortable with.
Be Happy & Enjoy Trading!!!
