I found this infallible ;
Do nothing for half an hour
watch the high and low
add and subtract 15 to both;
Example- I trade Nifty future so I watch Nifty for half an hour.Let us consicer friday's chart-during the first half an hour the highs and lows were6182 and 6050.Now we add and subtract 15 to each which comes to 6197 and 6035.
If the Nifty stays above 6197 for 15 minutes go long and if the Nifty stays below or at 6035 for 15 minutes,go short.I have been paper trading this for 6 months and found it infallible.
Practise will make u perfect. Wish you happy tradng. While doing so, also watch the emerging pattern and the imp fib ratios.
