# Full Trading Cycle Performance Profiling Script
# Wave 105 Agent 3
#
# This script runs comprehensive performance profiling of the trading cycle:
# 1. Compiles benchmarks in release mode
# 2. Runs validation tests to get P50/P99/P999 metrics
# 3. Runs full benchmarks
# 4. Generates flamegraph for bottleneck identification
#
# Usage: ./scripts/profile_trading_cycle.sh
