Description
Expected Behavior
When we redeploy a live algorithm, we don't lose the initial equity and profit from trades.
Actual Behavior
When we restart an algorithm, it doesn't take into account the initial cash from the first deployment, and the net profit of each security is lost.
Potential Solution
N/A
Reproducing the Problem
Deploy and algorithm, let it place trades and close positions to generate a net profit different from zero and redeploy: net profit is reset to zero.

Research direction
Start by reproducing the live algorithm deployment, trading, redeployment, and reset described in the issue, then trace where initial cash and per-security net profit are initialized or retained. Done means a redeployed algorithm preserves the initial equity and nonzero net profit from its prior deployment.
