Which trading action is recommended after an initial breakout in an extended rectangle trading strategy?

The correct approach after an initial breakout in an extended rectangle trading strategy is to add to the position on a pullback to the original resistance. In technical analysis, when a price breaks out above a resistance level, that level often turns into a new support level. By waiting for a pullback to this newly established support (original resistance), traders can increase their position at a more favorable price, ideally before a further upward move occurs. This strategy aligns with the principles of "buying the dip" after a confirmed breakout, where traders seek to capitalize on momentum while managing risk.

Additionally, this action reflects the bullish sentiment that typically follows a breakout, as it suggests that the market is likely to continue trending higher once it tests previous resistance levels that have now become support. Therefore, adding to the position during this pullback can enhance the potential for profit while still being mindful of the market's structure.
