I would recommend a top-down approach using multiple timeframes. Determine what the market and its sectors are doing first at different timeframes ranging from 60 down to 1 min. Explore how an individual stock's movements relate to the sector and market over these same timeframes. Is there any correlation ? Do some stocks move more than others compared to their sector/market ?
I no longer use volume extensively . I used to be very interested in the analysis called VSA - volume spread analysis. This was proposed by Tom Williams in his book "Undeclared secrets that drive the stock market", which was later revamped by Tradeguider software as "Master the Markets". However the market has changed since he drew up the original concepts and programmed trading results in the distortion of volume, such that it doesn't reveal what it used to reveal.
With regard to lowering your stops, one thing you can look at is volatility of a stock. This is traditionally measured by indicators such as ATR (average true range), which is effectively the average movement in price over typically a 14 bar range at the timeframe you are trading in. As long as the market retains its current characteristics then this will provide some measure of how far you can expect the stock to move in that timeframe. Still, I think it is better to have a more inteligent get-out, which recognises conditions are no longer suitable for the trade to continue, using the stop as last resort.
However you shouldn't lower your stops, because if the trade is really going against you the chances are that you have got the direction wrong or missed the exit signals and it is likely to continue that way. Get out when the loss is minor and then you can trade in the opposite direction if the right signals are there.
There is no shame and nothing to beat yourself up about in making a losing trade. There is shame in not having a pre-planned trading strategy or not following it.
