// MK Options Trader for NIFTY Options. 
// By Maheshwar Kanitkar 1-8-2012.
/* 

Here is trading plan.
Only Intraday Nifty Options trading and not overnight positions.
Time Frame 15 mins only.
Please plot ema 3 and ema 13 on charts provided by trading software or use popular charting products like Amibroker, Metastock, Metatrader.
Buy rule  = EMA 3 crossing EMA 13 from below, means EMA 3 > EMA 13. You can also use SMA 10 on crossover for confirmation.
Stop loss rule =  If price is above 60, 5-8% of high of last 3-5 candles, if price is below 60, 5% of  of high of last 3-5 candles.
Sell rule = EMA 3 crossing EMA 13 from above, means EMA 3 < EMA 13. ( not needed many times as Profit booking comes before). Remember sell  rule may come quite late from top, so you may be giving lot of profits by waiting for sell signal. If market is flat then sell rule will help you to keep in trade as you are trading on 15 min. Always sell below low. There will be many times you will find no new low and so you will stay in trade and can close trades on break even.
Profit booking rule = Trailing profit of 3% from current closing price, once hit exit or Close of current is less than Close of last candle by 3% or more or RSI 21 is above 70 or Fibonacci retracement levels for targets.
Broker – for more than 3 orders a day – use RKSV – monthly fix 1947/- for unlimited trades, unlimited lots, Zerodha for less than 3trades per day – 20 Rs. per order with unlimited lots or 1 lot a day use RKGlobal.
For selecting strikes, look at Nifty spot around 9:30 and select ATM strikes. For more risk and more profits you can select OTMs, if markets move fast, profits will be great.
Always buy above the high of signal bar by 1-2 Rs. (as per your comfort).
Never allow profits turn losses just because sell signal is not there.
Always keep SL in system with acceptable trigger. Remember this is Nifty, one movement on nifty can be of 30 -50 points in 1 min 
and you will be in deep losses, so never forget to keep SL in system.
Profit booking should ideally happen by trailing SL, which should also be in system. This helps to trail better.
There is nothing about options shorts in this system.
1 min & 5 min TF gives lot of whipsaws, do not try.
If you are using Amibroker then you will see green candle, SL line is drawn at 5%. Please set parameters as you wish. 
There are sound alerts on buy and sell bars so keep volume at medium level. 
Candles are colored as per formula and not as per candlestick patterns. On red candle, please sell below low.
