i wish to share my way of handling this.
i get daily a list of shares with trend value, support prices, resistance prices. normally when the trading starts, within 25 mins. the graph either shoots up or falls down. i allow this time and just watch. then watch for the scrips that are in negative and the scrips that are in positive. along with previous days high and low and volume. 5% up or down.
select some five scrips. if the scrip is in negative i go short for just one share. same manner where the scrip is in positive, buy just one share and watch. aided by the trend values, sup & resis. levels i keep adding the number of shares buying or selling. once i am happy with the profits i have made i close the trade and book profit.
for a beginner it is very difficult to keep watching more than 5 shares at a time.
i found that whatever may be value of the scrips the dif. between bought and sold price is the criteria. for a given amount at your disposal, it is better to go for a small value share and buy more number of shares, and the gain will be more.
as i am a novice, i am experimenting. i consider the loss is the tution fees i pay.
