Hi guys! I'm new to trading, been educating myself on indicators, chart patterns, etc,. They always teach you how to use them, their history, etc,. but they never seem to tell you how to choose the period for an indicator, for example: Stochastic Oscillator has the period K and period D set to 13 and 3 by default (default settings for the trading platform that I use) Why is that? Why is it 13 and 3? Does changing the period make any effect on the accuracy of the indicator? Does it depend on the time period of the chart? If the time period of the chart is in minutes, does that mean 13 period is 13 minutes and 3 period is 3 minutes? Also another thing that I've noticed is that some traders can predict the exact time the market is going to be bearish or bullish in the future, for example: at X time in the future, the market will be bullish. How do they do that? Is there an indicator for that or is it just an experience related thing? I've tried looking all this stuff up on YouTube and Google but nothing's been helpful so far. Could you guys please help me?
