What slippage really costs
Slippage is the gap between the price you asked and the price you got. On a strategy that trades often, a few points lost on every entry compounds into a meaningful performance drag — and the worst slippage happens exactly when spreads are widest: news spikes, session opens, thin liquidity hours.
Two guards, one goal: better fills
- Max spread guard: before executing, the EA compares the live spread against your per-account threshold. If the spread is wider, the order is rejected and logged — you skip the worst conditions instead of paying for them.
- Slippage cap: define the maximum deviation you accept on execution, so a fast market cannot fill you far from your intended price.
Both guards are optional and per-account: enable them where fill quality matters, disable them where you want unconditional execution.
Measure it, don't guess it
Every execution in AeronPilot records its full latency chain — signal received, server processed, EA executed, broker fill — plus the broker's reported ping and the achieved price. The Execution Quality dashboard aggregates it: average one-way latency, fill rate, slippage statistics per symbol.
That data answers real questions: is my broker slower on gold? Do my fills degrade during New York open? Should I move my VPS closer to my broker's servers (see how to choose a forex VPS)?

Frequently asked questions
Can I set a maximum spread per order?
Yes. Each account has a configurable max spread in points; orders arriving while the live spread exceeds it are rejected before execution and the rejection is logged with the observed spread.
Does AeronPilot reduce my broker's slippage?
No tool can change how your broker fills orders. What AeronPilot does is refuse executions in conditions where heavy slippage is likely, cap the deviation you accept, and measure your real fill quality so you can act on facts.
How is execution latency measured?
Each trade records timestamps at every hop — TradingView to server, server to EA, EA to broker — plus the broker ping, and the dashboard shows per-leg averages computed on filled orders only.
Do the guards work during news events?
Yes, and they pair well with the Economic News Guard: the news guard blocks the scheduled event window, while the spread guard catches any residual degraded conditions.
