PositionSizeCalculator - indicador para MetaTrader 5

Position Size Calculator - User Guide

Position Size Calculator tells you the exact lot to trade for the risk you choose. You place three lines on the chart (entry, stop loss and take profit), drag them where you want, and the panel shows the lot, the money at risk, the possible profit, the risk/reward ratio and the margin needed. It works on forex, gold, indices and CFDs because it uses the real tick value of each symbol.

1. Installation

1. Download PositionSizeCalculator.mq5 and copy it to MQL5\Indicators (in MetaTrader 5: File > Open Data Folder).
2. Open it in MetaEditor and press F7 to compile, or restart MetaTrader 5.
3. In the Navigator, drag PositionSizeCalculator onto any chart.

2. Quick start

1. Attach the indicator. Three lines appear around the current price: entry (gray), stop loss (red) and take profit (green).
2. Drag the stop loss line to where your trade idea is wrong, and the take profit line to your target.
3. Read the lot size in the panel and use it in your order.

3. The lines

• Buy or sell: stop loss below the entry means a buy, above means a sell. The panel shows BUY or SELL in the header.
• Market entry: by default the entry line follows the market price (Ask for a buy, Bid for a sell). The panel shows MARKET.
• Pending entry: drag the entry line to plan a limit or stop order. The panel shows PENDING and the entry stays where you put it.
• Selecting a line: the lines are selected when they appear, so you can drag them right away. If a line is not selected, double click it.
• Changing the timeframe keeps your lines. Each symbol has its own lines.

4. The panel

• Header: symbol, timeframe and trade side. Drag the header to move the panel. The - button minimizes it; minimized, it still shows the side and the lot.
• Lot size: the lot for your risk, rounded down to the broker's lot step, with the minimum lot and the step below it.
• Risk: your current risk with - and + buttons to change it without opening the inputs. Below it, the same risk in money.
• Risk : Reward: the ratio between the stop and the target. The red and green bar shows it at a glance.
• Levels: entry, stop loss and take profit prices with their distance in pips (points on symbols like gold or indices).
• Loss at stop / Profit at target: what you lose if the stop is hit and what you make at the target, with the lot shown in the panel and the commission included.
• Margin: margin needed for the lot and the part of your free margin it uses.
• Spread: current spread in points.
• Reset lines: puts the three lines back around the current price and returns the entry to market.
• Flip to sell / Flip to buy: moves the stop loss and the take profit to the other side of the entry, keeping the same distances.

7. Tips

• Always place the stop loss first, where your idea is wrong. Then let the calculator give you the lot. Never move the stop just to trade a bigger lot.
• Use "% of equity" if you usually have open trades, so the risk follows your real account value.
• If your broker charges commission, fill in "Commission per lot" so the loss shown is the real one.
• The lot is always rounded down, so the real risk is never above the one you set (except when the minimum lot is used).
