Grid Structure

Levels and spacing are one decision, not two. Twenty levels at 0.5% covers 10% of adverse movement; ten levels at 1% covers the same 10% with half the orders but twice the gap between fills. The first configuration cycles more often and books smaller profits; the second is cheaper in fees and reacts more slowly.

• Pick coverage from the instrument's realistic excursion — a few weeks of range on the chart is a better guide than a round number.
• Then pick spacing from the instrument's typical swing amplitude, so a normal wiggle actually crosses a level.
• Levels falls out of the two: levels ≈ coverage ÷ spacing.

A grid does not start flat. The engine takes a market entry at the base price sized init_lot batches, then covers it with init_grid_levels take-profit orders spaced one target step apart. In the ladder preview those exits are drawn as red dashed lines precisely because they are not ladder rungs — they are exits on capital you already committed.

1. 1
   Why open at all

   Without a base position a long grid would only ever have sell-side exposure after the first rung filled. The opening position gives the ladder something to sell into an immediate bounce.
2. 2
   Why several targets

   One target means the whole opening position exits at a single price. Three targets exit a third at +target%, a third at +2×target%, a third at +3×target% — capturing more of a strong move without predicting it.

   What it costs

   init_targets × init_lot × grid_size of notional, spent immediately. This term appears explicitly in the minimum-capital formula.

The fields are the same, but their meaning and their hints change with the selected mode:

• Growth modes — the Grid Levels hint reports the deepest rung's multiple, because depth now drives size as well as coverage.
• Decay modes — the hint notes that deep rungs floor at one lot, so beyond a certain depth extra levels add coverage but almost no size.
• Multi-order modes — the Initial Targets hint clarifies that deeper rungs derive their own target count from the mode, so this field only governs the opening position.
• Parametric modes — an extra block appears with just that mode's dial: ratio r, exponent p, slope m, step interval N, or the size cap.

Grid size is expressed in the strategy's notional currency and is converted to lots by the engine using the instrument's contract value and lot size. A grid size of 100 USDT on a contract worth 10 USDT is 10 lots; the engine floors to whole lots, so a grid size below one lot is rejected.
