Como rodar duas ou três estratégias ao mesmo tempo sem que uma atrapalhe a outra
Quick answer: adding a second strategy does not raise your expected return: it splits the same risk across two sources. What improves is smoothness — smaller drawdowns, fewer bad months — and only if the two do not win and lose together. If both trade the same index in the same direction, you do not have two systems. You have one at double size.
Pontos principais
- Total risk does not go up; it gets divided. Two systems at 0.5% each, not 1%.
- The benefit of combining is lower drawdown, not higher profit.
- If both strategies move together, the combination adds nothing.
- Each system needs its own log so you can switch it off on evidence.
What actually changes when you add a system
| What you expect | O que acontece |
|---|---|
| Double the profit | The same expected profit, split in two |
| More opportunities | More trades and more costs |
| Risk stays the same | Drawdown falls, if they are uncorrelated |
| Less work, since one is automated | More tracking: two logs, not one |
Correlation decides whether it helps at all
Say you have two strategies, each with a 10% standalone max drawdown, and you split capital evenly:
| How the two relate | Approximate combined drawdown | Worth it? |
|---|---|---|
| They win and lose on the same days | ~10% | No, it is one system |
| They often coincide | ~8–9% | Barely |
| Independent | ~7% | Yes, clearly |
| One wins when the other loses | ~5–6% | Yes, a lot |
Approximate, illustrative figures: combined drawdown depends on the exact sequence of results, not only on average correlation. Use them to compare scenarios, not as a prediction.
The kitchen-table test: put both strategies' monthly results in two columns and count how many months were negative in both at once. If it is more than half, you are not diversifying anything.
How to split the risk
| Active systems | Risk per trade for each | Total risk exposed |
|---|---|---|
| 1 | 1.0% | 1.0% |
| 2 | 0.5% | 1.0% |
| 3 | 0.33% | 1.0% |
The classic mistake is adding the second system while keeping 1% on each. That is not diversifying: it is doubling the risk and calling it prudence.
The full method — the overlap test on twelve months of results, the five axes that make a second system genuinely different, the account-level limits that must be shared, and a printable tracker — is laid out in the free ebook The Multi-Strategy Playbook.
When to add the second one
- The first has over 100 measured trades and positive expectancy.
- Your account can size at 0.5% without dropping below the minimum lot.
- The second trades a different instrument, a different session or a different logic.
- You genuinely have time for both, or one of them is automated.
- You keep separate logs from day one.
When to switch one off
A combined setup needs an exit rule as clear as its entry rule:
- Negative expectancy across more than 50 of its own trades.
- Its drawdown exceeds twice the worst in its own history.
- It has contributed nothing for months and only adds costs.
- It forces you to trade hours you cannot actually cover.
Switching off a system that is not working is not giving up. It is the decision that keeps the other one funded enough to continue.
The most practical case: one manual, one automated
This is the most common combination and the one that gets in its own way least, because the two operate at different moments and on different criteria. The Cortex Signal Kit covers the manual side with defined entry, stop and target, and Cortex Automation runs the automated side in MetaTrader 5 with its own risk and schedule, which keeps the two budgets separate instead of blended. To measure each one on its own there is the free ebook The Trading Journal Blueprint, and to test the automated side before allocating capital to it, the Automation Test runs five days.
How many strategies can I run at once?
Two is reasonable for most people; three if at least one is automated. Beyond that, tracking becomes the bottleneck.
Do I make more money by combining systems?
Not necessarily. You gain consistency, which is not the same thing but is usually more sustainable.
Can I run two systems on the same instrument?
Yes, if their signals do not coincide in time. If both buy US30 at the same hour, you are doubling one position.
Do they share the same daily limit?
Yes. The daily limit belongs to the account, not to each strategy, or you will lose twice as much on a bad day.
What if one is doing well and the other badly?
Resist moving capital quickly. Wait another 50 trades before changing the split.
