If you have a full-time job other than speculation, day trading will be hard to do. I think your 1-5 hold time is perfect for your situation.
Look into studying technical analysis. Learn price levels of support and resistance. Identify high volume areas and trade the charts. Make sure you develop trading strategies for each pattern you decide to trade.
If you are interested, I recommend reading
How I Made $2,000,000 In The Stock Market by Nicolas Darvas. He has a very interesting theory called the Box Theory which he applied to the stock market. His timeframe was also similar to the timeframe you are looking at. The book taught me alot about understanding price levels.
