*** This is not meant to be a support request for SC staff but rather a user discussion for anyone interested *** Hello folks, since there is no good answer on the topic I'm considering working on a method to replicate the LULD levels on a chart since SC does not provide official support for it (if SC engineers are reading *wink wink). So let's say you have EG the color bar based on alert, you could set it something like the following: OR( AND (C < AVERAGE(C[-5:-1])*1.20, ID11.SG1 > 3, AND(BARTIME > TIME(9, 30, 0), BARTIME < TIME(15, 45, 0)) ), AND (C < AVERAGE(C[-5:-1])*1.10, ID11.SG1 > 3, AND(BARTIME > TIME(09, 45, 0), BARTIME < TIME(15, 35, 0)) ), AND (C < AVERAGE(C[-5:-1])*1.20, ID11.SG1 > 3, AND(BARTIME > TIME(15, 35, 0), BARTIME < TIME(16, 0, 0)) ), AND (C < AVERAGE(C[-5:-1])*1.40, ID11.SG1 < 3, AND(BARTIME > TIME(9, 30, 0), BARTIME < TIME(15, 45, 0)) ), AND (C < AVERAGE(C[-5:-1])*1.20, ID11.SG1 < 3, AND(BARTIME > TIME(9, 45, 0), BARTIME < TIME(15, 35, 0)) ), AND (C < AVERAGE(C[-5:-1])*1.40, ID11.SG1 < 3, AND(BARTIME > TIME(15, 35, 0), BARTIME < TIME(16, 0, 0)) ) ) it checks the current price against the average in the past 5 minutes, with 10% or 20% levels depending on which time of the day we are, the price multiples here are for tier 2 stocks (small cap lets say), if you're are a large cap trader divide the levels by 2. ID11 (in this example) is the last day's close, since the levels change if it is < or > 3. It is in no way perfect since it is more complicated than this (see here: https://www.nasdaqtrader.com/content/MarketRegulation/LULD_FAQ.pdf where it says "Q: How are the reference price(s) that establish the trading bands going to be set?") but I'm unaware of how to render it within SC alertbox language. It is a 0.1 version so not definitive at all, all feedback is welcome! Have a great day. |
