Hi Apprentice,
The idea of self-updating candle Key level would be something that you would able to code as an indicator. Would work using the up and down swings from zigzag, would have 6 lines 3 for support and 3 for resistance (with colour options and price tags & alerts and labelled Current, TP 1 and TP2 and use different line options. This would self-update on the close of the candle need labels as the (current key level could show 1st signs of take profit or reversal)
As Support & Resistance key levels are calculated differently the resistance is from a ASK price so if price is below and touches would alert on an ASK price and if above on a BID price. The support is on a ASK price so if price is above and touches would alert on a BID price and if below on an ASK price. This would depend on the close of the current key level if a take profit or entry, The Alerts would pop up immediately and show buy or sell and the timeframe the key level was on
In a downtrend the key levels taken from previous outer highs uptrend using the BID price so if price closed below then this key level then this would be current and would have 2 more key levels below this current key level potential Take profits
In an uptrend, the key levels taken from previous outer lows downtrend using ASK price so if price closed above then this key level then this would be current and would have 2 more key levels above this current key level potential Take profits
Thanks Arf
In the screen shot above says would auto delete, now changed to having x3 levels each for the support x3 levels for resistance and self-update on close of candle through a key level auto deleting as moves to new level
