Overview

Trading Logic

• when a closed position has a negative net result (profit plus swap plus commission), the cumulative loss increases and the lot level rises by one, capped at the limit set by InpMaxLevel;
• when the net result is positive, the profit reduces the cumulative loss. The lot level is reset to zero only when the cumulative loss has been fully absorbed and reaches zero, returning the lot size to its initial value;
• until that reset happens, every new position uses the lot size that corresponds to the current level.

• if the signal direction flips, the pending order is deleted and a new one is placed in the opposite direction;
• if the direction is excluded by the trade direction filter, the pending order is deleted and the wait timer restarts;
• if price moves in the favorable direction, the pending price follows it — a buy stop moves down and a sell stop moves up — so the order trails the market instead of staying fixed.

State Persistence

• when enabled, the robot scans the outgoing deals of the last seven days that match the current symbol and the configured order identifier, and rebuilds the cumulative loss and the lot level, so the previous sequence can continue after a restart;
• when disabled, no rebuild is performed and both the cumulative loss and the lot level start from zero.

Risk Management

• Every entry carries an initial stop loss at the configured distance in points; a value of zero means no stop loss is attached.
• Optional trailing stop with separate trigger and distance parameters; setting either to zero disables the feature.
• The lot level has an upper limit set by InpMaxLevel. Once the limit is reached, the lot size is not increased further.
• Free margin is calculated before each order request. If free margin is insufficient, no order is sent, an entry is written to the log, and a cooldown period starts to avoid repeated failed requests.
• The filling mode supported by the symbol is detected automatically, with fallback retries when needed. Market orders and pending orders are handled separately.
• Trading sessions and symbol trade modes are checked, so no requests are sent while the market is closed and a cooldown is applied to reduce unnecessary error messages.
• Lot size is normalized to the symbol minimum, maximum, and step to avoid server rejections caused by precision.

On-Chart Panel

• Start​ enables automated trading. If there is no position, the first entry is attempted according to the current signal. Market-closed and insufficient-funds cooldowns are cleared.
• Stop​ stops new entries. Open positions are not affected and the trailing stop keeps running.
• Close All​ closes positions opened by this system on the current symbol, deletes pending orders, and stops automated trading. The cumulative loss and the lot level are not cleared by this action; to start from zero, disable state persistence and reload the robot.

Recommended Operating Conditions

• Symbol: instruments with good liquidity and stable spreads, such as major currency pairs, liquid crosses, precious metals, and major index CFDs. Verify on a demo account first.
• Timeframe: the robot can be attached to any chart; the signal timeframe is set by InpTF, M5 by default.
• Account type: both netting and hedging accounts are supported.
• Account size: because lot size increases after losses, the required capital is considerably higher than for a fixed-lot approach. Estimate capital from the total loss of a losing sequence that reaches the maximum level, not from a single stop loss. With the default settings (initial lot 0.01, additive mode, step 0.01, maximum level 10, initial stop loss 500 points), the lot size at the highest level is 0.11, and an account balance of at least 1000 USD or the equivalent is generally suggested on major currency pairs. In multiplicative mode, calculate the highest-level lot first: with the default multiplier of 2.0 and a maximum level of 10, that lot is about 1024 times the initial lot, which means about 10.24 lots from an initial 0.01 lot. In that case, either provide substantially more capital or reduce the multiplier and the maximum level. This is a capital-tolerance suggestion only and is not a performance expectation.
• Environment: use an account with stable execution and low latency, and keep the terminal online on a VPS so that state is not rebuilt incompletely after a restart.

Installation and Quick Start

1. Install the product from the Market or the Navigator; it appears in the Experts\Market folder.
2. Open a chart of the target symbol and attach the robot.
3. Set the initial lot, lot mode with step or multiplier, maximum level, initial stop loss, trailing stop, pending distance, and signal timeframe in the Inputs tab.
4. Make sure AutoTrading is enabled in the terminal and that the robot name with a smiley icon appears in the top-right corner of the chart.
5. Keep InpAutoStart set to true for an immediate start, or press Start on the panel.
6. Press Stop to halt new entries, or Close All to close positions and delete pending orders.

Testing Recommendations

• Download complete history for the symbol and test with real or custom spreads in the Strategy Tester. Pay particular attention to maximum margin usage and maximum drawdown during losing sequences.
• Run the robot on a demo account first to confirm lot level changes, pending order behavior, trailing stop behavior, and log output.
• Start testing with additive mode and a small maximum level. Only consider other settings once you are comfortable with the cumulative loss in a worst-case sequence.
• When running on several symbols in one account, use a separate chart per symbol and consider separate order identifiers to keep records clear.
• Before changing the lot settings, estimate the maximum loss per trade implied by the highest-level lot combined with the initial stop loss.

Limitations and Notes

• The robot manages only positions and pending orders on the current chart symbol that carry its own order identifier. Manual positions and orders from other programs are not affected.
• No take profit target is used; how much profit is given back depends on the trailing stop parameters.
• There is no built-in news filter, session filter, spread filter, maximum holding time, daily loss limit, or maximum drawdown limit.
• Lot size is not calculated automatically from an account risk percentage, so adjust it manually when the account size changes.
• State persistence reads the last seven days of deals only. After a restart or reload, results outside that window will not be reflected in the rebuilt values.
• The terminal must stay online. No requests are sent during disconnection, and the state after reconnection depends on the positions and orders that exist at that moment.
• Pending orders and stop loss modifications are involved, so actual fill prices depend on spread, slippage, and liquidity.

Risk Notes on Progressive Lot Sizing

• The longer a losing sequence runs, the larger the following lot becomes, and both margin usage and potential loss grow additively or geometrically.
• Multiplicative mode grows faster. The multiplier and the maximum level directly determine the largest lot, so calculate that value before deciding on account size.
• The initial stop loss is not the maximum loss. Gaps, slippage, and thin liquidity can all cause fills worse than the configured stop level.
• When free margin is insufficient, no order is sent and a cooldown begins, which interrupts the progression. Later profits may then not absorb the accumulated loss as planned.
• If this level of risk is not acceptable, reduce the maximum level, use additive mode with a smaller initial lot, or choose an approach that does not increase lot size after losses.
