EMA Cross Trade Alerts Strategy Diagram

This diagram trades upward and downward crossings of a 120-period fast EMA and a 450-period slow EMA on finished one-minute candles. A position snapshot gates each signal, fixed-volume market orders manage exposure, every own fill is written to the log, and the chart shows candles, both EMA streams, and buy and sell fills.

schema

Strategy Overview

Finished one-minute candles feed the fast EMA 120 and slow EMA 450. Formed-only filtering is disabled for both indicators, so their values are available from the beginning of the calculation.
The Crossing block emits true for an upward fast-over-slow crossing. A NOT block converts its false downward-crossing event into the sell-side trigger.
At each candle evaluation, the current position is released from a candle-triggered snapshot before the EMA signals are processed. Comparisons allow buying only when Position <= 0 and selling only when Position >= 0.
Both market-order blocks use NoCondition and a fixed Volume of 1. An opposite signal can reduce or flatten a position and can cross zero when its magnitude is below Volume, but it does not guarantee a complete reversal.
The Strategy trades block sends every own fill through the exact fill-message template to a Log notification. The chart receives finished candles, both EMA streams, and the buy and sell fill streams.

Entry and Exit Rules

Long entry: When the fast EMA crosses above the slow EMA and the candle-time position snapshot is less than or equal to zero, the diagram submits a market buy for Volume 1.
Short entry: When the fast EMA crosses below the slow EMA and the candle-time position snapshot is greater than or equal to zero, the diagram submits a market sell for Volume 1.
Exit: There is no dedicated exit or protection block. A later qualifying fixed-volume order in the opposite direction may reduce the current position, flatten an equal-sized position, or cross through zero when the position is smaller than Volume; a complete reversal is not guaranteed.

Parameters

Parameter	Default	Description
Candles	00:01:00	One-minute candle time frame; only finished candles drive the EMA and decision chain.
Fast EMA Period	120	Period of the fast ExponentialMovingAverage; formed-only filtering is disabled.
Slow EMA Period	450	Period of the slow ExponentialMovingAverage; formed-only filtering is disabled.
Volume	1	Fixed quantity supplied to both NoCondition market-order blocks.

Diagram Details

The Candles block emits only finished one-minute candles and drives the position snapshot before it feeds the EMA calculations.
Two Indicator blocks calculate ExponentialMovingAverage values with periods 120 and 450. Their formed-only option is false, and both outputs are also sent to the chart.
The Crossing output is true on an upward crossing and false on a downward crossing. A NOT Logical condition turns the downward event into a positive sell trigger; separate AND blocks combine direction and position.
The current Position is stored continuously and released once per candle before the EMA path. Comparison blocks evaluate Position <= 0 and Position >= 0 in the same causal candle wave as the crossing.
The buy and sell Modify position blocks place market orders with NoCondition and the shared fixed Volume value. No stop, take-profit, or separate exit block is present.
Strategy trades emits every own MyTrade. The String Formatter uses exactly EMA cross fill: {Order.Side} {Trade.TradeVolume:0.########} {Order.Security.Id} @ {Trade.TradePrice:0.########}.
The Notification block writes each formatted fill with Type Log and Caption EMA cross trade. The chart plots the candles, fast EMA, slow EMA, and separate buy and sell fill streams.
