Random Coin Toss Baseline Strategy Diagram

This diagram deliberately trades without a market signal. Whenever a finished four-hour candle arrives while the position is flat, a random value chooses between a long and a short entry. The position is held for ten more finished candles, closed at market, and the cycle can begin again on the following candle. It is an educational baseline for comparing rule-based systems, not a live trading strategy.

Strategy Overview

One finished-only four-hour candle stream clocks both the random decisions and the holding-period counter.
The Random block produces a value between zero and one. A threshold of 0.5 divides the range into two mutually exclusive directions.
The current position is sampled when each finished candle arrives and compared with zero. Both entry blocks also use the Open position condition, so a trade can only begin when the candle started with the diagram flat.
The entry trade activates an N values block, which counts ten subsequent finished candles before allowing the position to close.
The diagram uses no indicators, stop loss, or take profit. Its random sequence is not seeded inside the diagram and may vary between runs.

Entry and Exit Rules

Long entry: The random value is below the coin threshold and the position is flat. The diagram buys the configured volume at market.
Short entry: The random value is at or above the coin threshold and the position is flat. The diagram sells the configured volume at market.
Exit: Once an entry is filled, the diagram counts ten subsequent finished four-hour candles. The N values block then triggers a market close of the entire position. The exit candle does not open another trade; the next finished candle is the first opportunity to enter again.

Parameters

Parameter	Default	Description
Hold Bars	10	Number of finished candles counted after an entry fill before the position is closed; the value must be greater than zero.
Volume	1	Entry and exit order volume, in lots. The same configured volume is used to open and reduce the position.
Coin Threshold	0.5	Random values below this level select a long entry; values at or above it select a short entry.
Candles	04:00:00	Four-hour candle time frame used for entry decisions and the holding-period count; only finished candles are processed.

Diagram Details

The Candles output feeds the Random block, triggers the position snapshot, enters the Input socket of the N values block, and reaches the chart panel.
A Comparison checks whether the random value is at least the coin threshold. That signal selects the short branch, while a Logical condition in NOT mode produces the long branch.
The Position output feeds a triggered Variable that snapshots the position at the start of the candle. The snapshot is compared with a shared zero constant, and its flat-position signal joins the direction signal in each entry AND block. This snapshot prevents the closing candle from opening a new position immediately after the exit fill.
Both entry Modify position blocks use market orders with the Open position condition and receive their volume from one shared constant.
The MyTrade outputs of the long and short entry blocks feed the Trigger socket of the N values block. Further triggers are ignored while its ten-candle count is active.
The N values output triggers two Modify position blocks in Reduce only mode. The sell block can reduce only a long position and the buy block can reduce only a short position; both receive the shared volume, so only the applicable branch registers an exit.
The Chart panel receives the candle stream and the trades produced by both entry and both exit blocks.
