Opening a Short Trade with Percentage Risk and Reward Inputs

Article MQL5 code base
Read the original

Summary

The document describes a trading-platform script for opening a short position at the current chart price. When the script is placed on a chart, it prompts the user to set a risk percentage and a reward ratio; confirming the inputs submits the trade. The script is described as enforcing a maximum risk percentage of 20%. If an order does not execute, the user is directed to inspect the platform’s expert log for the failure reason.

This is a brief operational description of an order-entry utility, not a complete short-selling strategy. It does not explain how the stop or target is calculated, what account value or instrument data determines position size, or how slippage, fees, and gaps are handled. No tests, trade examples, or performance evidence are provided. The stated risk limit is a parameter cap, not evidence that a trade’s realized loss will stay within that percentage.

Key ideas

  • The script submits a short position using the current chart price.
  • The user can provide a risk percentage and reward ratio before submission.
  • The described risk-percentage input has a maximum limit of 20%.
  • Execution failures can be investigated through the platform’s expert log.
  • The document does not specify the sizing, stop placement, or target calculation rules.
