Optactic 2.5.4 is released.

In this release we made a few small but important changes.

First change, we added the cost of the strategy on the top of the chart. We found sometimes when you scroll the bottom controls, the cost of the strategy will be scrolled out of the window. The cost is actually important, and people need to watch the cost while adjusting the strategy. So we move it to the top, always visible.

Second, we added the profit for each position to the position table in the follow-up screen. (This screen appears when you click a created strategy in the strategy list). This will better help trader make decisions on the follow-up strategy, such as deciding which position to liquidate, which one to cut loss, etc.
