Along with the Supdem II indicator, this is by far the best utility ever created for MT4. There are many other trade by lines EA's / scripts out there but nothing comes close to this. Also the developer has been very accommodating with improvement requests.

hi, fantastic indicator - for the Breakeven Funktion i have an idea. Stop-loss = Breakeven Level. The idea behind is for the % trader. example: 8 pips = 1% risk. Breakeven after 8 pips - R:R 1 -(maybe there will be an option stop loss + x pips) - so if you have 20 pips 1% risk then break even is after 20 pips. That is better for trader with fix % risk so the break even level is always the same in % risk.

Must have. Simplifies everything and makes you aware for mistakes.

Fine EA to control risk and profit "on the move" and the coder keeps implementing the suggestions by the users. I bought a much more expensive one long time ago (not actively developed anymore) but this one is much handier to use. I too hope Ernestas will code an MT5 version for the future.

Everything I'm looking for, and more. Save me a lot of time

I purchased this EA which is really misnamed. It should be called: Lot Calculator & Adjustable Visual Order entry with stop, limit and market order tool and yes, a great strategy tester interface. I now use it for every trade and would hate to part with it. I hope the author is learning MT5 coding for when MT4 is discontinued in the near future.

Excellent product!!!
