How many micro contracts should I trade with Replikanto?

This article explains how to think about the number of micro contracts to trade with the Replikanto copier, and how Replikanto converts and scales contract quantities between leader and follower accounts.

There Is No Fixed Recommended Number

There isn't a strict recommendation on the exact number of micros to use with the Replikanto copier. The best choice depends on your account size, your risk tolerance, and your trading goals.

  • Micros suit smaller accounts and lower margin requirements.
  • Minis suit larger accounts seeking bigger position sizes.

Ultimately, the decision should align with your trading style and your comfort with risk.

How Replikanto Handles Micro and Mini Contracts

Replikanto supports copying trades between Mini and Micro instruments — and, starting with Replikanto 1.7.0.0, a third tier such as CME's E-nano contracts — through the Cross Order feature. When you use Cross Order, the number of contracts stays the same on both accounts — it converts the instrument, not the quantity.

  • 1 contract of ES on the leader becomes 1 contract of MES on the follower.
  • 10 contracts of NQ on the leader become 10 contracts of MNQ on the follower.

Built-in families include ES / MES / NES, NQ / MNQ / NNQ, YM / MYM / NDOW, RTY / M2K / N2K, GC / MGC / 1OZ, and CL / MCL / QM. Starting with Replikanto 1.7.0.0, a family can have up to three tiers, and the Cross Order square lets you pick which one each follower trades. The same 1:1 quantity rule applies to every tier. See Cross Order Instrument Map: Supported Futures and Tiers for all 36 families, and How to use Cross Order between Mini, Micro and Nano for the setup steps.

Scaling the Number of Micros with Ratio Copy

Because Cross Order alone keeps the quantity at 1:1, use the Ratio Copy Method if you want the follower to trade a different number of micros than the leader trades minis. You can define a ratio from -100 to 100 per follower account, which acts as a multiplier on the leader's order quantity.

  • Ratio 2.0 — leader sends 2 contracts, follower receives 4.
  • Ratio 5.0 — leader sends 1 contract, follower receives 5.
  • Negative ratio — reverses the direction; -1 hedges the leader 1:1.

Ratios below 1 are allowed, but the follower quantity is rounded down, and trades may not be copied when the resulting quantity isn't a whole number. You can check the calculation with this spreadsheet.

Practical Considerations

  • Account structure — it is generally better to have fewer accounts with larger balances than many accounts with smaller balances. Two 50k accounts are preferable to four 25k accounts.
  • ATM Copy — when combining Cross Order or Ratio Copy, enable the ATM Copy feature so followers manage their own exit orders.
  • Fill risk — combining Ratio Copy with Cross Order increases the chance of an order not being filled on one side, because the Mini and Micro instruments have separate order books and may not move exactly in sync during high volatility.
  • Multiple instruments — open a separate Replikanto window or tab for each instrument you copy.
