Who this is for — Anyone operating across markets who wants a less fragile structure. If one asset class is flat or hostile, others may offer setups.
Multiple instruments describes coordinated use of different assets (indices, forex, commodities, crypto, bonds…) in the same operational process. Adding instruments only makes sense if it improves return/risk — not to «fill» trading time.
In plain terms — Don't depend on one market: if one sleeps, another can work.
Instrument selection
| Criterion | Why |
|---|---|
| Correlation | Macro shocks unify — check rolling ρ |
| Liquidity | Slippage and size on illiquid markets |
| Competence | Don't trade markets you don't understand |
| Hours | Session overlap vs sleep/work |

Combined exposure control
- Many instruments without unified model = hidden leverage
- Dashboard: risk contribution by asset class and strategy
- Pair with gross exposure and aggregate risk
Typical mistake — Adding tickers without unified risk model — 5 positions, 1 beta factor.
Example — Index futures + forex + commodities: in equity stress, commodities reduce drawdown synchrony.
Summary card
- Rule: every new instrument passes correlation + liquidity test.
- Cap: max exposure per asset class.
- Review: monthly P&L and risk contribution per market.
