In my opinion the easiest way is to follow your trading system and strategy strictly. Then take profit and stop loss orders will work for you, making sure to minimize your mistakes as much as possible. Reading too many analytics as well as the trading system will only increase your mistakes.
Yes, a good trading system is very important. But this is not enough for success. A key tool most successful traders use is a trading journal. I would recommend a google document spreadsheet. You can edit it anywhere, all the PCs on which that document is open gets updated as well
