..dont you 'Sir' me Manoj........I am learning as much as anyone else here, though the mode is a bit different.
Coming to filters...there are 2 reasons for not mentioning filters:
1. Specifying the filter here would result in everyone taking it, leading to bad price fills at the action points. If you traded the 60min system, you would know what I am implying.
2. All learners of this method are encouraged to do some backtests on their own..and derive at the filter most appropriate for use in Nifty as wel as stocks. Giving it here would be promoting a particular filter..maybe akin to spoonfeeding.
3. If you go to the mother thread of miniflow..u would know the filters which were is use....For nifty it had been 14/7/5, though most would have changed these by now.
