# DCA Futures Bot Calculator

> Anti-liquidation calculator for DCA (Dollar-Cost Averaging) trading bots on cryptocurrency futures exchanges. Calculates safety order progressions, liquidation prices, and minimum wallet reserves for leveraged trading.

## Usage

The calculator is available as a web app at https://dcacalc.com/

All inputs can be set via URL query parameters:

https://dcacalc.com/?coin=BTC&long=1&wallet=5000&bo=20&so=15&count=6&leverage=125&dev=1.4&vol=2&step=1.4&dump=5

### Parameters

- `coin`: Trading pair base currency (e.g. BTC, ETH, SOL). Paired with USDT.
- `long`: Direction. Accepts: `1`, `true`, `long`, `yes` for Long. Accepts: `0`, `false`, `short`, `no` for Short.
- `wallet`: Wallet balance in USDT.
- `bo`: Base order size in USDT (margin cost, NOT leveraged position size). With leverage=125 and bo=20, margin is 20 USDT but position size is 2,500 USDT.
- `so`: Safety order size in USDT (margin cost, NOT leveraged position size). Same as bo — this is what you pay from wallet, not the total position.
- `price`: Entry price in USDT. Optional — defaults to current market price if omitted.
- `count`: Number of safety orders (0-100).
- `leverage`: Leverage multiplier (1 to coin's max, e.g. 125 for BTC).
- `dev`: Price deviation percentage per safety order step (0.2-20).
- `vol`: Volume scale — multiplier for each subsequent safety order size (0.1-10).
- `step`: Step scale — multiplier for deviation growth between safety orders (0.1-10).
- `dump`: Additional price dump/pump percentage after last safety order (0-99).

## Key Concepts

- **Base Order (BO)**: The initial order that opens the position. The `bo` value is the margin cost in USDT (wallet deduction), not the leveraged position size. Actual position size = bo × leverage.
- **Safety Order (SO)**: Additional orders placed at lower (long) or higher (short) prices to average the entry. Like BO, the `so` value is the margin cost. First SO uses this value; subsequent SOs are scaled by the volume scale multiplier.
- **Deviation**: How far price must move from entry before each safety order triggers.
- **Volume Scale**: Multiplier that increases each subsequent safety order's size.
- **Step Scale**: Multiplier that increases the deviation gap between safety orders.
- **Liquidation Price**: The price at which the exchange force-closes the position.
- **Maintenance Margin Rate (MMR)**: Exchange-defined margin requirement, varies by coin's max leverage tier.
- **Total Reserve**: Minimum recommended wallet balance to avoid liquidation through all safety orders plus additional dump.
