Vectorithm YHigh Retest

Vectorithm YHigh Retest EA

Overview

Vectorithm YHigh Retest is a simple breakout and retest Expert Advisor that trades only one idea.

1. Price must break above yesterday’s daily high.

2. Price must retest the yesterday high area.

3. Price must close back above the level again to confirm the retest.

4. Then the EA opens a Buy trade.

This EA is designed to trade the chart symbol you attach it to. It does not scan multiple symbols.

Trading Logic

Step 1. Calculate yesterday’s range

At the start of each broker day, the EA reads:

• Yesterday High from the D1 candle shift 1

• Yesterday Low from the D1 candle shift 1

It can also draw a rectangle that shows yesterday’s high and low range across the current day.

Step 2. Breakout detection

The EA waits for a candle close above yesterday’s high by a buffer.

• Breakout level = Yesterday High + BreakoutBufferPoints

If the last closed candle close is above this level, the EA marks a breakout as detected.

Step 3. Retest detection

After breakout, the EA waits for a candle that touches a retest zone around yesterday’s high.

• Retest zone top = Yesterday High + RetestTolerancePoints

• Retest zone bottom = Yesterday High - RetestTolerancePoints

A retest is detected when a candle’s high and low range overlaps this zone.

Step 4. Entry confirmation and Buy

After the retest, the EA requires confirmation.

• Entry level = Yesterday High + EntryBufferPoints

If the last closed candle close is above the entry level, the EA attempts to open a market Buy order.

The EA opens only one position at a time for the symbol and MagicNumber.

Trade Filters and Safety Rules

Spread filter (optional)

If enabled, the EA checks current spread before entering.

• If spread is above MaxSpreadPoints, it will not trade.

Trade permission checks

The EA will not trade if trading is disabled in:

• The EA input EnableTrading

• Terminal trading permissions

• Account trading permissions

• MQL trade permission flags

Random trade gate (sigmoid filter)

Before placing a trade, the EA generates a random percent from 0 to 100 using a sigmoid distribution.

• The trade is allowed only if the value is less than or equal to MaxSigmoidTradePercent.

This is a built in randomness filter that can reduce the number of trades.

No Stop Loss, no Take Profit, no trailing

This version places Buy trades with:

• Stop Loss = 0

• Take Profit = 0

There is no trailing stop and no break even.

Daily position closing rule

Close at new day

When the broker day changes, the EA closes any open positions that belong to:

• The current chart symbol

• The EA MagicNumber

This happens once per day when the EA detects a new daily start.

This means trades are intended to be intraday and are not held across daily rollover.

Chart Visuals

Yesterday range rectangle (optional)

If enabled, the EA draws a rectangle for each day that spans:

• Time: from today start to the next day start

• Price: from Yesterday High to Yesterday Low

Old rectangles are automatically deleted after KeepRectDays.
