Define the underlying thesis

A longer-horizon position usually rests on an enduring thesis. State the expected development, observation horizon and evidence that would invalidate it. A long holding period is not a substitute for a clear rationale.

Include carrying costs

Assets, futures and CFDs have different holding mechanics. Overnight financing or rollover can materially affect a prolonged position. Compare these costs and the committed capital alongside the expected price movement.

Reassess before adding exposure

Adding to an adverse move increases exposure without validating the thesis. Revisit the assumptions and predefined limits first. Gaps and major events can also produce exits different from the original plan.

Compare holding periods

In a practice example with an assumed constant daily charge, compare three days with thirty days and calculate the accumulated difference. Real charges can vary. The exercise simply exposes how small daily amounts can become meaningful over a longer holding period.
