The long-vs-short split takes the same KPIs you read at the account level — trade count, win rate, expectancy, profit factor — and computes them separately for buy-side (long) trades and sell-side (short) trades. The two sub-tiles sit next to each other so you read them as a comparison, not as standalone numbers. A profitable account can quietly hide a losing short side: the long side carries the average up while the short side bleeds.
What the split tells you: - Symmetric (similar win-rate + expectancy on both sides) — the edge is direction-agnostic. Likely a clean trend-following or mean-reversion setup. - Long-only profitable — you're either in a long-biased market regime (everything goes up) or your short-side execution is weaker. Audit short stops + entry timing. - Short-only profitable — rarer; usually a sign you trade choppy / declining markets and the long side is forcing into trends that aren't there. - Only one side has trades — you're not actually two-way trading. The other side's edge is unknown, not zero. Don't claim a two-way edge from one-way data.
TradeOnyx renders the Long vs. Short card on the Overview tab as a single two-pane comparison. When one side has zero trades, the card shows a soft hint reminding you a two-way edge only proves itself once you actually take both sides — it doesn't pretend a one-way history is a two-way validation. Pair the per-side reading with the Trades-tab direction filter to drill into the underperforming side's setups one click later.
