Here's an indicator that you might find useful - Snorm Trade Lines. You move the entry and stop loss lines, to suit your planned trade, the lot size is calculated for you, based on your selected risk % and account balance (or equity or a fixed amount). There is also an alert option for when price gets close to your entry level; as well as an option to move the target line to a fixed R:R based on your stop and entry.
It's been tested on a few brokers without any problems but let us know if you find any bugs on your broker.
Hope you find it useful ...
Snorm trades only with GKFX and has no hesitation in recommending them, for tight fixed spreads and quick execution (even during NFP, from personal experience).
