One GC matches one CFD lot, and that is the problem
Spot gold at one standard lot is roughly $100 per $1 and $10 per 0.10. COMEX GC is $100 per $1 on 100 ounces. The numbers rhyme, which is why traders paste a 0.80 to 1.45 lot band onto a futures account and end up with one full contract. A $35 range, a normal gold day, is then $3,500. The trail is $3,000. The trade can be directionally right after having already ended the account on the way.
Micro gold, MGC, is $10 per $1. A $35 move is $350. Five micros are half a full contract and $1,750 on that same range, still large, but no longer automatically fatal. Bot controls should be told the contract is GC or MGC, not XAUUSD, before they accept a size.
A $5 stop on full gold is $500 and often too tight
A structural stop of $5 to $7 is $500 to $700 on one GC and $50 to $70 on one MGC. The cash open and the COMEX bell run stops of that tightness on the full contract. If the structure is $15 away, one GC risks $1,500, half the trail, and a slip makes it worse. Three MGC on a $15 stop risk $450. That is a trade the $3,000 trail can survive twice.
Expert attempts that try to clear a $6,000 target with one GC swing are using the product that can lose the trail on a single wick. Open a Venasri account and set the contract cap to micros unless the dollar math is already under about $400.
Flat on Friday, and careful on funded Tier-1 mornings
You must be flat before the Friday afternoon CME close. A GC position over the weekend is a rule breach, and a $20 gap is $2,000 on the full contract. There is no FX triple swap to calculate. There is a gap and a deadline. Evaluation news is allowed. Funded Starter and sim-funded tiers restrict Tier-1 releases, and gold is where CPI slippage shows up in dollars per ounce.
Starter also watches a 40% best day. A full-contract winner of $2,500 is already above 40% of a $6,000 target. The micro that keeps the loss survivable also keeps the winner from owning the cycle. The end-of-day mark, around 4:10 PM ET or 5:00 PM ET, is when an open gold runner becomes the trail input.
Do not let one ounce path spend the account
Equity Guard on $100,000 should flatten near $2,250, which is less than the $3,500 a $35 GC day can print. If you are in the full contract, the guard is racing a product that can gap through it. Prefer the micro so the guard is a backstop rather than the only stop. On a $50,000 plan the trail is only about $1,500 to $2,000, and one GC is even less appropriate.
CME message limits still apply if you trail the metal tick by tick. Place the structural stop, partial at planned prices, and leave the order. The first $10,000 of later funded profit pays at 100%. It pays only if the gold contract you chose was small enough to lose.
