At TOP ONE Funding, traders must maintain consistent position sizing based on a dynamic lot parameter rule that updates after every trade.
How Lot Parameters Work
The first trade opened on the account establishes the initial lot size reference.
All subsequent trades must remain within a ±1 lot range relative to the previous trade.
The allowed lot size range is recalculated after each trade based on the most recent executed trade.
Allowed Lot Size Range
For every trade:
- Minimum Lot Size: Previous trade lot size − 1 lot
- Maximum Lot Size: Previous trade lot size + 1 lot
Examples
If your first trade is 2 lots, the next trade must be between 1 and 3 lots.
If the following trade is 3 lots, the next trade must be between 2 and 4 lots.
If the next trade is 1 lot, the following trade must be between 0 and 2 lots.
Each new trade resets the allowed range based on the immediately preceding trade.
Important Notes
This rule applies from the first trade onward.
Lot parameters are evaluated trade by trade, not on averages.
Trades executed outside the allowed lot range may be considered invalid or inconsistent.
Violations may result in trade invalidation, payout adjustments, or denied withdrawals.
