Workflow & logicWorkflow & logic

GoldenRobber is a two-sided DCA grid for XAUUSD with no hard stop-loss. Each round (R{n}) starts with an Init, grows through Adds whenever price travels MinPips, and is closed piece by piece through per-order TP, Tia clusters, or flattened in one go by Global TP. All logic lives in four MT5 event handlers:

The ticket map stores ticket → round, add#, DCAPos/DCANeg, position type, comment so the EA can recognise its rounds after a restart. Priority chain in OnInit:

1. Local file GR_TicketMap_<magic>.csv (Common folder) — only tickets that are still open are loaded.
2. If the map is still empty, cloud sync is on and this is not the tester: Cloudflare (InpCloudCfDomain), then MyApi (InpCloudMyApiDomain); a successful load is written back to the local file.
3. TicketMapRebuild() rebuilds from the comments of open positions.

1. GR_LinkPump() on every timer event (200 ms) when Link is on: drains frames and pulls config when signalled (see EA Link).
2. Heavy work is gated to 1 s (measured with GetTickCount64): CloudSyncPulse() then UpdateInfoPanel().
3. CloudSyncPulse() self-throttles to InpCloudSyncIntervalSec (10 s in pass58): sends the heartbeat (leader status + config), then only the leader pushes the ticket map to Cloudflare and MyApi.

Thanks to the timer, panel and heartbeat keep running in a quiet market. Since 1.42 b3 the CloudSyncPulse interval is measured with GetTickCount64(), so periodic heartbeats keep running while the market is closed. Older builds (≤ 1.42 b2, production b21, b21.1) still have deviation D1 (EA-HOTRELOAD-STANDARD.md §17): they measure with TimeCurrent(), so heartbeats stop without ticks and the web shows Offline.

The order below is exactly as in OnTick(). The order matters: closing logic (Global TP, Tia…) runs before any new orders, and Close all short-circuits everything after it.

GoldenRobber 1.42 b3 OnTick() flow. Heartbeat and EA Link run separately in OnTimer().

EventKillTimer() → close EA Link (Close("deinit")) → TicketMapSaveImmediate() (writes the file; with cloud sync on it sends a heartbeat and, if leader, pushes the map to Cloudflare + MyApi) → deletes panel, S/R zones, pivot lines → releases every indicator handle. Open positions are not closed.

A round is the bookkeeping unit: every order carrying the same R{n} in its comment. Typical comments: Init R12 P |init_minpips, DCAPos R12 B#3 |add_minpips, DCANeg R12 S#1 |add_sr, Hedge R12 |hedge. Full tag list: Order Comment Tags.

Leader only, and only when a new M1 bar has just started. Steps in source order:

1. Manual Init Pause (4) / Close all (5) → return immediately, no Init. This is the highest-priority block.
2. Tag init_strong with g_strongMoveBypass on → determine the strong bar's direction (bypass).
3. Trend filter + ApplyInit with a neutral trend → stop (unless Manual Init is not OFF or StrongMove bypass applies).
4. Direction label labelDir = trend direction (EMA InpTrendFilterMAPeriod on InpTrendFilterTF ± NeutralPips); if neutral, the colour of the last closed M1 bar. StrongMove bypass or Manual BUY/SELL override it.
5. Trend filter + ApplyInit → keep only the P side (UP: Buy, DOWN: Sell).
6. Per side: Multi-TF (HTF must agree, neutral = block) → Pivot (Buy near Support, Sell near Resistance) → Wick rejection → Choppy ADX (blocks both) → Dual-Direction (choppy + only one side open → block the other) → Anti-Whipsaw cooldown (blocks both). Multi-TF, Choppy, Dual-Dir, Anti-Whipsaw and Adaptive NeutralPips only act while the Choppy Defense Group is active (pass58: ≥ 24 non-hedge positions).
7. StrongMove bypass → force exactly the bar's side. Manual BUY/SELL → force exactly the chosen side.
8. SingleRoundMode → apply the per-side flags from ProcessNewBarEntries.
9. OpenInitRoundPosNegPair() re-checks Pause/Close all, InpDCAPos/NegMaxTrades, exposure scale, lot ≥ min lot; increments g_roundId and sends Init R{n} P / Init R{n} N.

• P = with-trend leg using DCAPos lot/TP. N = counter-trend leg using DCANeg. UP: Buy = P, Sell = N; DOWN: Sell = P, Buy = N.
• Without trend ApplyInit an Init opens a P + N pair. With it (as in pass58) only the P leg opens in practice.
• InpDCANegEnable is not checked at Init — it only disables the DCANeg Add branch. An N leg can still open if the filters allow both sides. Not under pass58: InpTrendFilterApplyInit=true means a directional trend opens only the P leg and a neutral trend opens nothing — live data contains no DCANeg order.
• GetRoundInfo() infers the round type from comments: counts Init P/N labels, then DCAPos/DCANeg; on a tie (Init with both P and N) it follows the current trend. The round type selects the Add branch.

Runs on every tick (leader). Fully blocked when: flash crash active, InpMaxTotalLot reached, Friday after InpFridayNoInitAfterHour (with Weekend Protection on), sideway (unless lot balancing), bar range < InpInitMinBarRangePips, or Auto Balance in ACT with no side needing balance. Then it walks every round:

• Pacing: ≥ InpAddCooldownSec since the last Add (0 = timing profile or InpWaitAfterCloseSec); at most InpMaxAddsPerBarPerSide per M1 bar (0 = unlimited); after one successful Add the loop stops until the next call.
• Caps: SingleRound max adds per side, InpMaxOrdersPerRound, InpDCAPos/NegMaxTrades (0 = unlimited; lot balance may exceed it with InpLotBalanceBypassMaxTrades), price zone.
• DCAPos (with price): Add Buy when ask ≥ highest Buy + MinPips; Add Sell when bid ≤ lowest Sell − MinPips (a missing side borrows its ref from the other side).
• DCANeg (against price): Add Sell when bid ≥ highest Sell + MinPips; Add Buy when ask ≤ lowest Buy − MinPips. Skipped entirely when InpDCANegEnable=false (pass58).
• MinPips: InpDCAMinPipsMode Fixed = InpDCAPos/NegMinPips; Pivot = max(Floor, K × half pivot range of InpDCAMinPipsPivotTF). S/R is only an extra condition (tag add_sr) unless InpSRGateAdd=true makes nearness mandatory.
• Add filters: Trend ApplyAdd (UP Buy only, DOWN Sell only, neutral blocks both), Multi-TF ApplyAdd, Pivot ApplyAdd, Wick ApplyAdd, Choppy ApplyAdd. The side that needs lot balancing is exempt.
• Lot: DCAPos = StartLot × Multiplier^n, DCANeg = StartLot × Multiplier^(n−1), capped at MaxLot, times the exposure scale. Legacy (InpDcaChainPersistent=false, pass58): n = same-side positions currently open in the round, so the lot can reset smaller after Tia/TP closes some. Persistent: n = highest B#/S# ever reached, reset only when the whole round dies — see DCA chain persistent.

pass58 example, DCAPos Buy round: Init 0.10 → Add 0.15 → 0.22 → 0.33 → 0.50 (cap), 34 pips apart (lots normalised to the broker's volume step).

CheckHedging() every 5 s (leader, g_hedgeEnable). ByMainRound / ByTotal / ByAccountProfit: when non-hedge Buy count ≥ g_hedgeAfterTrades, the Buy side is losing and there is no Sell hedge → open a Sell Hedge |hedge sized by mode (e.g. ByTotal = g_hedgeLotPercent % of total Buy lots); mirrored for Sell. PerRound: one hedge per qualifying round (Hedge R{n} |hedge). Hedges bypass the exposure scale, are excluded from rounds/counters, and close via Global TP/SL, Tia or Close all. pass58: off (InpHedgeEnable=false, InpHedgeAfterTrades=9999). Parameters.

The state is computed in ProcessAddEntries: requires g_lotBalanceEnable and |Buy − Sell| > min lot. Normal: ACT when |net| > g_lotBalanceTrigger. LossTriggered: only once equity has dropped ≥ InpLotBalanceLossTriggerUSD from the reference equity (the reference rises with equity and resets on ACT → WAIT). InpLotBalanceUseTargetLevel=true keeps ACT until |net| ≤ g_lotBalanceTarget. While ACT: new Inits blocked, normal Adds blocked, only lighter-side Adds allowed (exempt from trend/pivot/wick/choppy/sideway), and CheckLotBalance() opens AutoBal Direct orders of up to InpLotBalanceMaxLotPerOrder every InpAddCooldownSec (0 → 60 s). pass58: off. Parameters.

Samples the bid every second into an InpFlashCrashWindowSec ring buffer. A move ≥ InpFlashCrashPips versus any sample in the window → active for InpFlashCrashCooldownSec: virtual TP and Tia frozen, every Init / Add / CheckLotBalance blocked, Auto Balance forced, and FlashCrashFastBalance() opens lighter-side orders every InpFlashCrashBalanceIntervalSec (up to InpFlashCrashBalanceMaxLot) until |net| ≤ max(min lot, target). pass58: off. Parameters.

With g_weekendProtectEnable (server time): on Friday from InpFridayNoInitAfterHour Inits and Adds are blocked, and with g_weekendBalanceEnable one lighter-side BalanceFri order per M1 bar (up to InpWeekendBalanceMaxLotPerOrder, skipped above 80 positions) until |net| ≤ g_weekendMaxNetLot; on Friday from InpFridayCloseAllBeforeHour everything is closed if total profit ≥ InpFridayCloseMinProfitUSD; on Monday before InpMondayNoInitUntilHour Inits are blocked. pass58: off. Parameters.

An operator tool, set with InpManualInit in the .set or the hot-reload key manual_init on /admin/easupported/goldenrobber. Enum values in 1.42 b3:

MQL5 inputs are immutable at runtime, so every hot-reload key has a global initialised from its input in OnInit, and the logic reads only the global. The server sends values in the heartbeat response; the EA pushes config_schema on every heartbeat so the web can render the form.

How the server applies and reverts (TicketMapParseHeartbeatResponse):

1. Every key present in the response is written into its global (manual_init is range-checked; strong_tf must be a valid TF).
2. hot_keys is a CSV of the keys the server is currently overriding for this account (by composite_id + magic). When the field is present, every key not listed is reset to its input value — that is how Clear on the web actually removes an override. A response without hot_keys reverts nothing.
3. The panel line Hot Reload: … is rebuilt from the applied keys.
4. Only then is leader state read (is_leader, current leader, alive nodes).

Known deviation (D4): keys are looked up in hot_keys by substring without comma delimiters. The schema's default values are constants in code, not the loaded .set values (e.g. hedge_enable defaults to true while pass58 = false).

Without Link, new config only arrives with the next heartbeat (InpCloudSyncIntervalSec). 1.42 adds a TLS TCP channel to EaLinkBroker (port InpLinkPort, default 9607). The channel carries only a signal {"t":"cfg","rev"}; values are always pulled over the HTTPS heartbeat because MT5's SocketTlsHandshake does not verify certificates. Authentication is a challenge + HMAC-SHA256 over sha256(token); the raw token never crosses the socket.

• GR_LinkPump() runs every 200 ms; it pulls a heartbeat when a cfg is pending and ≥ 1 s has passed since the previous pull (debounce). Logs [EaLink] cfg rev=… đã áp trong N ms.
• Right after reconnecting (hello_ok), if the last OK heartbeat is older than 5 s → one catch-up pull.
• Reconnects with 2 → 60 s backoff ±20%; bad_sig / unknown_ea wait 300 s; 60 s of silence closes the link. Broker down → the EA keeps working like b21.1 on periodic heartbeats, panel shows Link: DOWN.
• The Link host must be in Allow WebRequest. Protocol details: EA-HOTRELOAD-STANDARD.md §9 · EA integration standard · Realtime brokers.

Used when the same account + magic runs on several terminals/VPSes for redundancy. Leader = the alive node with the lowest InpCloudNodePriority (ties broken by the smaller node_id); alive = heartbeat within InpCloudHeartbeatTimeoutSec. CanTradeAsLeader() returns true when cloud sync is off, in the tester, or when the node is not a follower.

• Leader-gated: Init, Add, CheckLotBalance, flash-crash fast balance, hedging, Tia, virtual TP, Global TP / SL / Clear Stuck, residue clean, Close all, and pushing the ticket map to the cloud.
• Not leader-gated (checked in code): CheckWeekendCloseAll, CheckWeekendBalance, the close-all branches of CheckMaxDrawdown and CheckDailyLimit, clearing the cloud map when the local map becomes empty. All of these are off in pass58.
• Fail-safe: never had a successful heartbeat → leader; both Cloudflare and MyApi failing for more than 2 × InpCloudHeartbeatTimeoutSec → the node claims leadership so positions are not abandoned.
• Every node needs a distinct priority and should set InpCloudNodeId explicitly (the auto ID changes when the terminal folder changes). Details and failover scenarios.
