$RSR |Breaking through the 0.002 level
Before looking at position sizes, understand the key price levels.
Previous highs and lows are the most common reference points. The memory of a price failing to rise or finding support there last time often influences buying and selling when it returns to that level.
When a price revisits a level after several days, people who entered around that price before may break even and exit or add to their positions, so trading volume is often concentrated there.
Don’t change your original pace just because of a particular number, and never use borrowed money to test a prediction.
