Cross-Instrument Signal Strategy Diagram

This diagram synchronizes finished four-hour TONUSDT@BNBFT and BTCUSDT@BNBFT candles. TONUSDT supplies a 20-period rate-of-change signal, while BTCUSDT supplies its own 20-period simple moving-average filter. The diagram is intended to run with Strategy Security set to BTCUSDT@BNBFT; an internal 0/1 flat/long latch, shared entry-permission state, and fill-driven protection then manage that long-only exposure.

Strategy Overview

Two independent security variables configure only the TONUSDT and BTCUSDT four-hour candle subscriptions. Their finished candles are aligned before a decision, so the TON momentum value and BTC trend filter always belong to the same synchronized interval.
TON ROC(20) is bullish above zero and becomes an exit condition at zero or below. BTCUSDT is eligible for entry when its Close is at or above SMA(20), and a Close below SMA(20) is an exit condition.
A long entry requires all four conditions at once: TON ROC(20) > 0, BTC Close >= BTC SMA(20), the internal state latch reports flat, and the shared Cooldown is ready state permits entry. The externally assembled AND then triggers a NoCondition market buy with Volume 1.
The entry action clears the shared entry permission and starts Entry Cooldown N, while a discretionary signal sell clears the same state and starts Signal-exit Cooldown N. The corresponding timer restores permission after eight synchronized candle pairs; a generation check suppresses completion from an older timer after a newer reset. Exits never wait for this state, and protection exits do not reset it.
The BTCUSDT market-buy fill switches the latch to long and arms percentage protection with a 2% take-profit and a fixed, non-trailing 2.5% stop-loss. A discretionary close fill or Take/Stop activation and fill switches the latch back to flat. The strategy never opens a short position.

Entry and Exit Rules

Long entry: On a synchronized finished four-hour pair, the external entry AND triggers a NoCondition market buy with Order Volume 1 when TON ROC(20) is above zero, BTC Close is at or above BTC SMA(20), the state latch reports flat, and shared Cooldown is ready permits entry. The action trades the selected Strategy Security, which must be BTCUSDT@BNBFT to match the Traded Security candle parameter.
Short entry: There is no short entry. The discretionary sell uses ReduceOnly, MarketOrder, and Volume 1, so it can only reduce the selected Strategy Security exposure; Take and Stop protection likewise close the long exposure.
Exit: When the latch reports long, TON ROC(20) <= 0 or BTC Close < BTC SMA(20) triggers the ReduceOnly market sell without waiting for the shared cooldown state. A 2% take-profit or 2.5% fixed stop-loss can also close the exposure with a market order; the stop does not trail.

Parameters

Parameter	Default	Description
Traded Security	BTCUSDT@BNBFT	Security used only by the traded-instrument candle subscription. Set the selected Strategy Security to the same BTCUSDT@BNBFT value because actions and strategy trades use Strategy Security.
Signal Security	TONUSDT@BNBFT	Security used only by the signal-instrument candle subscription; its momentum contributes a signal and no action is addressed to this variable.
BTC Candles Series	04:00:00	Finished four-hour BTCUSDT candle series used for Close, SMA(20), state decisions, and the chart.
TON Candles Series	04:00:00	Finished four-hour TONUSDT candle series used for ROC(20) and synchronized decisions.
BTC SMA Length	20	Period of the SimpleMovingAverage calculated from finished BTCUSDT candles.
TON ROC Length	20	Period of the RateOfChange calculated from finished TONUSDT candles.
ROC Threshold	0	Zero level used to distinguish the positive momentum entry state from the non-positive signal exit state.
Entry Cooldown N	8	Number of synchronized candle pairs counted by the entry-action timer before it can restore shared entry permission.
Signal-exit Cooldown N	8	Number of synchronized candle pairs counted by the discretionary signal-exit timer before it can restore shared entry permission.
Order Volume	1	Fixed quantity used by both the NoCondition market buy and the ReduceOnly market sell for the selected Strategy Security.
Take Profit	2%	Percentage gain from the filled entry price that activates take-profit protection.
Stop Loss	2.5%	Percentage loss from the filled entry price that activates stop-loss protection.
Trailing Stop Loss	false	Disabled, so the 2.5% stop-loss remains fixed rather than following favorable price movement.
Use Market Orders	true	Enabled, so take-profit and stop-loss protection close the position with market orders.

Diagram Details

Separate security Variable blocks feed only the independent TONUSDT@BNBFT and BTCUSDT@BNBFT candle subscriptions. The order actions and Strategy trades use Strategy Security instead; select BTCUSDT@BNBFT there as well, so it matches the Traded Security candle parameter.
Two Candles blocks emit only finished four-hour candles. A Sync block pairs the two streams at 04:00:00 before either instrument enters the decision chain.
An Indicator block calculates RateOfChange 20 for TONUSDT, and another calculates SimpleMovingAverage 20 for BTCUSDT. Comparison blocks express the positive/non-positive ROC states and the BTC Close relations above or below its average.
A numeric Unit Variable acts as the state latch: 0 means flat and 1 means long. Buy MyTrade writes 1; discretionary sell MyTrade plus Take/Stop activation and MyTrade events write 0. Logical-condition blocks combine that state with the synchronized signals.
Two action-specific N-values timers hold Entry Cooldown N and Signal-exit Cooldown N at 8. Either action clears one shared entry-permission state; its timer may restore Cooldown is ready after eight synchronized pairs, while a generation check rejects stale completion from an earlier timer. The external flat-entry AND has one cooldown input. It triggers a buy Modify position action configured as NoCondition, MarketOrder, Volume 1; the signal exit triggers a separate ReduceOnly, MarketOrder, Volume 1 sell without that input.
Position protection receives both buy and discretionary-close fills: the buy fill arms Take Profit 2% and fixed Stop Loss 2.5%, while the close fill clears stale protection state. Trailing Stop Loss is false and Use Market Orders is true. The chart receives both synchronized candle streams, BTC SMA(20), TON ROC(20), Take and Stop order streams, and all BTC fills from Strategy trades.
