Averaging

Averaging, or averaging down in a long and averaging up in a short, adds size while the trade is wrong. The average price improves, which means you need a smaller bounce to get back to flat. The risk does not improve. You now lose more if the original stop is hit, and traders who average often move that stop, which is how a planned small loss becomes a large one. Averaging is not always irrational. A systematic scale-in, with the full size and the final stop defined before the first order, is a planned entry in pieces. The dangerous version is the unplanned add, done because being red is uncomfortable and a better price feels like a repair.

If you intend to scale in, write the prices, the sizes, and the final invalidation before the first fill. The total size at the full scale-in must already satisfy the risk budget at the final stop. Then the early pieces are not a reason to add beyond the plan, and a move through the stop flattens everything. If you did not write that plan, you do not get to invent it after the loss. One add, maybe, is a judgement you will have to own. A series of adds that doubles and doubles again is a refusal to take a loss. The market does not know your average price. The support you liked does not move closer because your average did.

The only averaging worth defending is the pre-planned scale-in at a level you wanted, where the first fill was a starter and the second was the real entry, both above the stop. Use it sparingly, in liquid instruments, at a size that is boring. Do not use it to repair a broken setup, a breakout that failed, a level that closed through. Once the invalidation prints, adding is not averaging. It is a new trade against the evidence, using the open loss as an excuse. Flatten, and if the setup reappears later, it is a fresh ticket at a fresh size.

Averaging because a guru said professionals buy dips. Professionals also have a last price where they are out, and they are not averaging the same idea in five names at once. Also calculating the new breakeven and treating it as the target. Getting back to flat is not a market level. And hiding adds in the journal so the original trade still looks small.

Averaging assumes the market will return toward your price. Trends are the markets that do not. A long campaign of averaging down a downtrend is how accounts are disabled. Even a planned scale-in fails when the level gaps through the final stop and the whole size is in. If you cannot take that full loss without breaking your rules, the plan was too big. There is no later add that fixes a risk budget you already exceeded.
