Anyone trade MGC vs YG recently and have any info on stop order slippage on either?

@Futures Operator,

Good question, and the landscape has shifted significantly since this thread started.

MGC vs GC - The Current Reality (2024-2025)

The MGC vs GC decision has become much cleaner in recent years. MGC (micro gold futures) hit a single-day record of 741,822 contracts in October 2025, and the CME metals complex overall reached 2.1 million contracts that same day. That volume translates to real liquidity.

For slippage specifically: during active sessions (London open through US close), MGC spreads tighten considerably. Most retail traders report minimal slippage on market orders during these windows. Stop orders execute cleanly when you are not trying to trade the overnight session or during major news events.

YG vs MGC - Why MGC Wins Now

YG (mini gold on ICE) has largely been abandoned by retail traders. ICE raised their data fees substantially, and the volume migrated to CME products. If you are comparing micro gold vs gold futures options today, MGC is the clear choice for smaller position sizing. The difference between gold and gold mini contracts comes down to liquidity, and CME owns that market.

The Numbers That Matter

• MGC: 10 troy oz, $1.00 per tick, ~$1,700 margin
• GC: 100 troy oz, $10.00 per tick, ~$15,000 margin
• Front month always has best liquidity for both

Should I Trade MGC or GC on TopStep?

For prop firm traders wondering about MGC vs GC futures on TopStep specifically: be aware that each micro contract counts as ONE FULL CONTRACT toward your position limits. A 50K account with 5 contract max means 5 MGC maxes you out, same as 5 GC would. The risk per tick is obviously different ($1 vs $10), but the position counting treats them equally.

TopStep's Maximum Loss Limit calculates end-of-day, not intraday trailing. This gives you room to work through drawdowns during the session, which matters in gold's volatile moves.

Practical Recommendation

For traders comfortable sitting on hands and waiting for clean setups (which your post history suggests you value), MGC offers enough liquidity now that slippage should not be a primary concern. The real question is whether the $1/tick movement gives you enough reward for your edge, or whether you need GC's $10/tick to make your risk-reward work.

The GC vs MGC choice ultimately depends on your account size and risk tolerance, not liquidity concerns. Both contracts move identically, just at different dollar amounts.
