Thanks AW10.
I was thinking about buying/selling Just In the money Calls. Which means that if the price is 5050, I buy 4900 Call and Sell 5000 call.
I wouldn't do that right now, because premiums are way too high. But the Max gain/max loss ration would typically be 0.8
Maybe I should look at changing the Exit position/stop loss position to Make RR as 2/1. The problem of backtesting is OI historical data is not available.
I did go thru your NR7 system, before you wrote this post. I found it from link in yur signature. I made an excel sheet from Jan 2003 to last month and marked the signals - simple formula really, no fancy programming was required.
After that I got stuck. From your thread, I gathered two things -
a) If it is a NR7th day (you can guess by 3:00 pm), go for a straddle. Next morning, sell the losing side. Keep the winning side open, or hedge it (partly)
b) If it is NR 7 day, on 8th day see the way the market goes. If it pierces the earlier day's high, Buy Call. Wait. If it pierces the low (from above) sell call and buy put.
I got a lot of dates on my spreadsheet as NR7 days and NR4 days. But after that I am stuck. The signals are confusing. Sometimes it works, sometimes not. Not yet able to give a clear picture about it.
About Using OI, I would like to calculate PCR myself rather than one by NSE. NSE PCR considers Puts and Calls for ALL Strikes including way off strikes. I would like to consider only serious strikes.
If current price is 5050, I would take 4900,5000,5100 and 5200 strikes. If it is 5100 as current price, I would take 4900-5300 strikes (5 levels)
Another good indication is Nifty Futures. A Very High premium or even a small discount tells the way money is pouring in.
PCR and Nifty Future Premium/Disc only tells about market expectations and buildup. If the market goes contrary to that signal, it will continue to go contrary, because its momentum is assisted by entities hastily trying to square off their positions. Somehow, there has to be a way to find out whether the bears/bulls are trapped and are about to cover up or not. Yet to find it though.
