On Signature 100K it trails the highest daily close and locks once it reaches the initial balance; on Zero 100K the calculator lets it trail without locking, the stricter reading, because the pages read disagree on whether it locks during the challenge.

Does E8 Markets have a daily loss limit in the challenge?

According to the E8 Markets help center read on 2026-10-10, neither Signature 100K nor Zero 100K has a daily loss limit in the challenge; the Signature 100K daily pause exists only on the Performance account. Positions are closed every day (by 23:00 server time on Signature 100K and at 15:10 CT on Zero 100K), so none are held from one day to the next.

What it computes and assumes

Each synthetic day has your trades per day; across them, the share that wins your average win is your win rate and the rest lose your average loss. With decimals, some days have one more trade than others so the average is yours.
The report's simulator resamples those days and checks every daily close: first the daily limit, then the total one and last the target with the minimum days. Every day with trades counts as a trading day, even when it nets zero.
Every win and loss has the average size: no tails, slippage, costs or intraday floating loss. Real losses vary, so with a real history the limits are usually hit more often.
Trades are independent: no streaks longer than chance.
The rules are those each firm posted on the date shown; they may have changed.
We keep your figures in no database or file; since they travel in the link, the server's access log may hold the address requested. It is a calculation with declared figures, not an audit or a forecast.

With your real history

With your real history, the simulator uses your actual days, the floating loss at each daily close and the costs: upload your file. The report resamples your own days with the firm's rules, compares the published firms and tries the sizes.
