I'm now thinking of an alternative system with only red line and green line of KST on 100 minute charts without EMA 20. (Edit: I may make a new post in the future with a revised version of the system once I'm certain that there won't be missing images.)
Red line is above 0.00, exit long when green line dips below 0.00 before the candle closes; re-enter/pyramid longs when green line returns to being above 0.00 after the candle closes.
Redline is below 0.00, exit shorts when green line rises above 0.00 before the candle closes; re-enter/pyramid shorts when green line returns to being below 0.00 after the candle closes.
Price and EMA 20 may be used for confirmation/refining the trades. The green line of KST tends to react earlier than waiting for a 100 minute candle to close with EMA 20 (it would have saved me a bit of money if I had been certain this earlier today
) which can lead to heavy losses on days with extremely strong fundamental news.
Edit: If the green line of KST or CCI is not available, as soon as the price touches EMA 20, exit a trade, when a candle closes in the previous direction of a trade (price above ema 20 for longs and redline is above 0.00; or price below ema 20 for shorts and redline is below 0.00) re-enter or pyramid.
