Intraday trading strategies (formulae)

Hi fellow traders,

I don't understand this strategy, can anyone please explain in a more simpler language. If there is any other method based on trend line, resistance and support, previous day high and low, I will be glad to learn it. I am a frustrated trader since 2007. I lost my money, other people's money and borrowed money. For any assistance my e-mail is [email protected] THANKS AND GOD BLESS.
 
Hi, I have created an excel for the 30 min trading strategy:

How to use this excel:

1. delete the data in the cells in the "Open" columns highlighted in yellow. these are the values taken for 15th October.

2. Copy the contents of the bhavcopy for the previous day from the nse website and paste them in the "Yesterday" worksheet overwriting the entire contents.

3. Manually enter the "open" prices of today's stock quotes in the "open" column in yellow. I don't know how that can be done automatically, unless someone shares this info.

4. The buy/sell signal will be generated automatically with the corresponding target price. Where there is no buy/sell signal you can ignore the stock for that day.

I am not sure if my excel is accurate. If there are any errors I would appreciate your feedback on it... thanks
