$BR fell below the 0.4 level.
Let’s talk about what lies behind this number.
Common ways to confirm whether a breakout is valid include: closing on the other side of the level, failing to break back through it on a retest, and seeing trading volume pick up during the breakout.
Many people use key levels as a reference for position sizing: which side of the level they hold a position on and where they place their stop-loss are more practical considerations than predicting whether prices will rise or fall.
Calculating trade size based on the stop-loss distance is far more reliable than picking a position size arbitrarily.
