RiskSizer Panel Lite MT4 - Risk Percent Lot Calculator With One Click Buy Sell - MetaTrader 4のためのエキスパート

RiskSizer Panel Lite (MT4) — Risk% Lot Calculator + One-Click BUY/SELL

RiskSizer Panel Lite is a lightweight MT4 trading panel that helps you calculate an estimated lot size from a fixed risk percentage of your account balance, using two draggable horizontal lines on the chart as your SL/TP zone. It also includes one-click BUY/SELL execution for fast manual trading.

Key Features

• Risk-based lot sizing by % of Account Balance.
• Two draggable chart lines (LOW / HIGH) to define your SL and TP levels quickly.
• One-click trading: BUY / SELL.
• Editable Risk%:
  • Click the Risk% box and type your value
  • Enter = Apply, Esc = Cancel
  • Use + and - buttons for quick adjustment (step size configurable)
• Live preview on the panel:
  • Symbol
  • Spread (points)
  • Risk money (account currency)
  • Calculated BUY lot / SELL lot
  • LOW/HIGH line prices
• Reset button to restore default SL/TP line distances around current price.
• Optional Max Spread filter to block trades when spread is too high.

How It Works

• The panel uses two horizontal lines on the chart:
  • LOW line = lower price line
  • HIGH line = higher price line
• BUY logic: Entry = Ask, SL = LOW line, TP = HIGH line (only if HIGH > Ask)
• SELL logic: Entry = Bid, SL = HIGH line, TP = LOW line (only if LOW < Bid)

Inputs / Parameters

• Risk % per trade (InpRiskPercent)
• Risk step (InpRiskStep)
• Default SL points (InpDefaultSL_Points)
• Default TP points (InpDefaultTP_Points)
• Max spread (points) (InpMaxSpread_Points) — 0 disables the filter
• Deviation (points) (InpDeviation_Points)
• Magic number (InpMagic)
• UI refresh (ms) (InpUiRefreshMs)

Notes

• This is a Lite tool designed for simplicity and fast manual execution.
• Risk is calculated from Account Balance (not Equity).
• Lot sizing engine is intentionally simplified (approximate calculation for universal symbols).
• Please test on a demo account before using on real accounts.
