Here's an indicator that can help being more disciplined.
It will show price zone on a chart that satisfies a stop/target or minimum Risk/Reward criterion.
How does it work ?
First, you select your target and stop prices by moving the green and red lines. You can quickly toggle short/long configuration by pressing spacebar.
The indicator has 2 settings : ConstantStopTarget and MinRR
In ConstantStopTarget mode, you enter you maximum stop and minimum target as parameters (StopTicks and TargetTicks), the indicator shows the entry zone that satisfies those conditions.
In MinRR mode, you enter minimum RR (MinRR) that qualifies for a trade. The indicator will show the price zone that satisifies your minimum RR condition.
