Update Saved Algorithm

update_algo

Update a saved algorithm owned by the user (and sync any linked instances). Only supplied fields change. Accepts strategy updates via strategy_params OR flat top-level fields (indicators, buy_conditions, sell_conditions, buy_exit_conditions, sell_exit_conditions, stop_loss_percentage, take_profit_percentage, etc.).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

`strategy_type`	No	Optional top-level strategy type (CUSTOM, MA_CROSSOVER, RSI_OVERSOLD_OVERBOUGHT, MACD, BOLLINGER_BANDS) if not inside strategy_params.
`buy_conditions`	No	Optional top-level LONG entry conditions (ANDed). Accepts condition dicts or shorthand strings such as ['Price > EMA(50)', 'EMA(9) crosses above EMA(21)', 'RSI(14) < 40', 'ADX(14) > 20'] or 'Price > EMA(50) AND EMA(9) crosses above EMA(21)'.
`risk_percentage`	No	Optional top-level risk % per trade (0.1 to 100.0).
`sell_conditions`	No	Optional top-level SHORT entry conditions (ANDed; opens a short, does not close a long). Accepts condition dicts or shorthand strings such as ['Price < EMA(50)', 'EMA(9) crosses below EMA(21)'].
`strategy_params`	No	Full strategy block (accepts nested object OR JSON string, or you can pass flat top-level fields on create_algo): { strategy_type: 'RSI_OVERSOLD_OVERBOUGHT' \| 'MA_CROSSOVER' \| 'MACD' \| 'BOLLINGER_BANDS' \| 'CUSTOM', indicators: [{type: 'SMA'\|'EMA'\|'WMA'\|'LWMA'\|'SMMA'\|'VWMA'\|'DEMA'\|'TEMA'\|'HMA'\|'KAMA'\|'RSI'\|'MACD'\|'Bollinger Bands'\|'VWAP'\|'ADX'\|'STOCH'\|'ATR'\|'CCI'\|'WILLR'\|'MFI'\|'OBV'\|'ROC'\|'KC'\|'DC'\|'ICHIMOKU'\|'PSAR'\|'SUPERTREND', period?: number}], entryConditions: { buyConditions: [{indicator1: {type, period, component?}, relationship: 'Crosses above'\|'Crosses below'\|'Is above'\|'Is below'\|'Is equal to', indicator2: {type, period, component?} OR {type: 'Value', value: 30}}], sellConditions: [...] }, exitConditions: {buyExitConditions: [...], sellExitConditions: [...]} (optional), risk: {stopLossPercentage, takeProfitPercentage, riskPercentage, maxDrawdown, trailingStopEnabled, trailingStopAmount, allowPyramiding, maxPyramidPositions}, closeOnBiasFlip: boolean (optional) }. buyConditions open a LONG; sellConditions open a SHORT (they do NOT close a long — use exitConditions.buyExitConditions to close longs). Entry conditions are ANDed; exit conditions are ORed. MACD operands take component 'line'\|'signal'\|'hist'; Bollinger/KC/DC operands take component 'upper'\|'middle'\|'lower'; ADX takes 'adx'\|'plus_di'\|'minus_di'; STOCH takes 'k'\|'d'; Ichimoku takes 'tenkan'\|'kijun'\|'senkou_a'\|'senkou_b'. Use {type: 'Price'} for the bar close (or priceType 'open'\|'high'\|'low'\|'hl2'\|'hlc3'\|'ohlc4'). At least one of buyConditions or sellConditions must be non-empty. movingAverages is accepted as an alias for indicators. Shorthand strings like 'EMA(9) crosses above EMA(21)' or 'RSI(14) < 30' are also accepted. Example indicator sets (do not default to one): RSI period 14; SMA 50+200; EMA 12+26; MACD; Bollinger length 20; ADX 14; VWAP; Stochastic 14. Never invent EMA 9/21 when unspecified.

A3.7/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare this is a non-read-only, non-idempotent, non-destructive mutation, so the safety profile is covered. The description adds context that annotations cannot express: the update cascades to linked instances, and unspecified fields are left untouched. It still omits whether changing strategy fields affects running instances or open positions, and what failure modes occur.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with the action and the key partial-update constraint before the input-form detail. The parenthetical field list is a mild duplication of schema content but is short enough not to bloat the description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present and 100% schema coverage, return values and per-field detail need not be repeated, so the description covers the essentials. For a 30-parameter mutation tool with cascading side effects it is still thin on what the linked-instance sync actually does and on validation failure behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so per-field meaning is already handled, giving a baseline of 3. The description earns the extra point by stating the equivalence between the nested strategy_params object and the flat top-level fields (indicators, buy_conditions, sell_conditions, exit conditions, risk fields) — a cross-parameter relationship the schema cannot convey on its own.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ("Update a saved algorithm") and adds ownership scope ("owned by the user") plus a side effect ("sync any linked instances"). It does not explicitly distinguish itself from siblings like update_linked_algo, update_instance, or create_algo, but the resource and ownership qualifier are enough to select it.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It states the partial-update contract ("Only supplied fields change") and explains that strategy data can be sent either via strategy_params or flat top-level fields, which is practical guidance for choosing an input form. However, it never states preconditions (the algo must already exist and be listed via list_my_algos) or when to prefer this over update_linked_algo/update_instance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
