T-DCA: Tiered Dollar-Cost Averaging

T-DCA stands for Tiered Dollar-Cost Averaging. It is a structured form of DCA: instead of buying a fixed amount on a fixed schedule, it pre-plans a finite ladder of price-triggered entries with tiered sizing, tracks the averaged entry price, and keeps a take-profit order resting on the exchange. Every tier is known before the first order is placed.

Tiered. Each entry in the ladder has its own trigger price and its own size. In the base T-DCA ladder, later tiers are larger than earlier ones, so more capital is deployed after price has already fallen rather than spread evenly over time. That is the difference from time-based DCA, which buys the same amount at the same interval regardless of price.

A typical DCA bot either buys on a schedule or keeps adding safety orders as price falls. T-DCA fixes the ladder in advance — the number of tiers, the gap between them and the size of each tier — so the maximum position is known from the start, and it exits with a take-profit order placed on the exchange rather than on a timer. It does not remove market risk: a leveraged position can still lose if price keeps falling past the last tier.

Blitz Trading is a DCA trading bot whose ready-to-run presets are built on T-DCA. It ships ready-to-run T-DCA strategies that you can copy and edit, a free in-app backtester that replays your settings (long setups) on 1-minute candles for curated symbols (up to a year where data is available), and a 3-day Bybit demo (paper-trading) trial on a Bybit account opened through the Blitz link — all running on your own exchange account: one-click OAuth on Bybit, Gate.io, KuCoin and Bitget, a manually created API key on BingX, and a wallet connection on Hyperliquid. Other DCA bots can approximate a tiered ladder with safety orders; check whether their ladder is finite and where the exit order lives.
