((due to editing done comments by jyotixxx came before my post, hahahaha!!!!))
i've downloaded data from 15/11/2007 to 30/12/2011, and it was in other format than which i had so i didn't combine them, and kept the new data in another data base and did testing on the data.
the data has some errors, i think, like on 18/5/09 it has only one data line of 11.55 and it has gapped above prv close. but still for working out my doubts regarding the long term profitability of this system, i did some more testing on some old and bad period data.
this time i did testing differently by not putting back all the profits back into the system
this way of testing with initial capital of 15000 (no trades be missed if we lose simultaneously), on 10% margin, so that only 1 minifty can be bought, or 2 lots during the period when it came very low, and no investing back the profits,
1. the profits during the period 1.4.11 - 6.7.12 was 526%
this was my initial backtesting result, with only 1 mini, which i wanted to work out my doubts about its long term profitability,
2. jan 08 - dec 08 profits were 360.41%
3. jan 09 - dec 09 profits were 332.09%
4. i didn't understand why the system traded only 10 trades in 2010, whereas in the charts lot of trades have occured (see next post )
5. jan 11 - dec 11 profits were 236%
6. composite period (my new data period) from 15.11.07 - 30.12.11 (4 years) gave profits of 918.28%
this has removed the doubts regarding the profitability of this system and now ' aankh mund ke khel sakte hain '.
more ideas r requested from seniors and newcomers, to improve during the whipsaws, i ve tried a lot but not finding a better way.
