ARMFAveraging a position and martingale
Averaging down a losing position improves the average entry price and increases the loss in money at the same time — those are two sides of one action. Martingale takes the idea to its limit: the volume is doubled after every loss. We look at the arithmetic of both schemes and at exactly where they break.
Averaging a position in forex and what it does to the account
Averaging is adding volume to a position that is already in the red. The average entry price improves and the break-even exit point comes closer. At the same time the volume grows, and so does the cost of every next pip of movement against you.
An example in numbers. A buy of 0.10 lots at 1.0900. The price goes against the position; at 1.0850 another 0.10 lots is added. The average price is 1.0875, and break-even is now 25 pips away instead of 50. But the volume has doubled, and every next pip costs $2 instead of $1.
| State | Size | Average price | Loss at 1.0850 | The cost of 1 pip |
|---|---|---|---|---|
| The first entry | 0.10 lot | 1.0900 | −$50 | $1 |
| After averaging | 0.20 lots | 1.0875 | −$50 | $2 |
| The price fell to 1.0800 | 0.20 lots | 1.0875 | −$150 | $2 |
| A second averaging at 1.0800 | 0.30 lots | 1.0850 | −$150 | $3 |
| The price fell to 1.0750 | 0.30 lots | 1.0850 | −$300 | $3 |
Every move of 50 pips costs more than the previous one: first $50, then $100, then $150. A position that started with a risk of $50 carries a loss of $300 after two averagings — and the price has covered only 150 pips.
Averaging and building a position are different things
A planned build-up of a position in parts is sometimes confused with averaging, although the two actions are opposite in meaning.
The formal sign that separates one from the other: if the total risk on the position after an addition does not exceed what you counted before the entry, it is a plan. If it does exceed it, it is averaging, whatever it is called.
Martingale in trading: why the scheme looks like a winner
The classic martingale: after a loss the stake is doubled so that a win covers all the previous losses. The scheme gives many small wins and a rare large loss — and that is exactly why it looks like it works for the first few dozen trades.
| The number of the trade in the streak | The volume with a start of 0.01 lots | Cumulative loss at a stop of 30 pips |
|---|---|---|
| 1 | 0.01 | −$3 |
| 2 | 0.02 | −$9 |
| 3 | 0.04 | −$21 |
| 4 | 0.08 | −$45 |
| 5 | 0.16 | −$93 |
| 6 | 0.32 | −$189 |
| 7 | 0.64 | −$381 |
| 8 | 1.28 | −$765 |
| 9 | 2.56 | −$1,533 |
| 10 | 5.12 | −$3,069 |
Ten stops in a row with a share of winners of 45 % over a stretch of two hundred trades is not an exotic event: the chance of meeting it is about 20 %. By the tenth trade the required volume is 512 times the starting one, and the accumulated loss exceeds $3,000 with a start of three dollars.
Exactly where the scheme breaks. In two places at once: either the deposit or the permissible volume runs out (the margin for 5.12 lots at a leverage of 1:100 is about $5,100). Martingale does not reduce the probability of a loss, it changes its distribution: many small wins and one loss the size of the account.
A planned build-up versus averaging: one trade, two approaches
The difference is visible in numbers. Take an account of $5,000 and a risk rule of 1 % — $50. The idea: buying EUR/USD in the 1.0850-1.0800 zone with a cancellation below 1.0780.
| A planned build-up | Averaging after the fact | |
|---|---|---|
| The entry levels | 1.0850 and 1.0800, defined in advance | 1.0850, then 1.0800 — because it went against |
| The overall stop | 1.0780 for the whole position | 1.0780 or lower, «we'll see» |
| The volume calculation | A total risk of $50 across both parts: 0.03 + 0.04 lots | Each part at 0.07 lots «as usual» |
| Actual risk | $50, that is 1 % | $154, that is 3.1 % |
| What decides the outcome | Whether the idea is right | Whether the deposit is enough to sit it out |
Both positions look identical in the terminal: two buys at different prices. The difference lies entirely in whether the total risk was counted before the first entry. It is the only sign that separates one from the other — and the same sign explains why «I am just adding by the plan» often turns out to be untrue.
Frequently asked questions
Is averaging always a bad thing?
Not always, but almost always dangerous in margin trading. The difference between a planned build-up and averaging after the fact is whether the total risk was counted before the entry. If it was and it fits your limit, it is part of a strategy; if the decision was taken with the position open, it is a reaction to a loss.
Are martingale and averaging different techniques or the same one?
They are not the same. Averaging builds up one and the same position, martingale raises the stake in the next trade after a loss. They have one thing in common, and it is the main one: the volume grows after a loss, that is, the risk increases exactly when the account has already shrunk.
Do martingale expert advisors work?
They give a smooth equity curve until the first sufficiently long streak — and a collapse on it. A smooth stretch is not evidence of reliability: it is exactly what the scheme is supposed to show between its rare large losses.
How do you correctly add to a profitable position?
In such a way that the overall risk of the position does not exceed the original one: along with the added volume the stop is pulled up. Then even on a reversal the position closes no worse than the calculated loss, and if the move continues the result is noticeably higher.
What is averaging a position in trading in simple words?
It is adding volume to a position that is already in the red. The average entry price improves, the break-even exit point comes closer — and at the same time the loss in money grows, because every next pip of movement against you costs more.
How do you count the average price when averaging?
As a volume-weighted average: (price₁ × volume₁ + price₂ × volume₂) ÷ the total volume. For two equal parts that is a simple average: buys at 1.0900 and 1.0850 give an average of 1.0875, and break-even is 25 pips away instead of 50.
Why is martingale especially dangerous in forex?
Because of leverage and a round-the-clock market. Leverage lets the volume be doubled for longer than an account without it would allow, and continuous trading makes it possible to keep the streak going without a pause. As a result, the moment when either the deposit or the available margin runs out arrives sooner.
Are there safe averaging schemes?
There are no safe ones, there are counted ones. If the levels for adding and the overall stop are set before the entry and the total risk fits the rule, it is a planned build-up of a position. Everything else is a reaction to a loss, and its danger is that the limit is not known in advance.
What do I do if the position has already been averaged and is going further into the red?
Count the current total risk and compare it with the rule. If it has been exceeded, the decision is simple and unpleasant: cut the volume down to the permissible one, taking part of the loss. Waiting for a reversal here is not a strategy but a hope.
Can averaging be used in forex if the position has no leverage?
Formally the risk is limited by the amount invested, but the economics are the same: adding increases the loss in money and pushes the exit decision further away. The absence of leverage removes the threat of a stop-out, not the mistake in managing risk.
Does averaging differ from adding by a grid?
Grid schemes are formalised averaging: the levels are set in advance, but the total risk still grows as the price moves against the position. The key question is the same: is there a level at which the whole construction is closed, and has the loss at it been counted.
