njjstocks 8 posts msg #161210 - Ignore njjstocks	7/11/2024 11:28:38 AM Any pointers on how to implement an if function in SF? Here's the psudo logic : set{bear_fvg_sum, sum(if(bearish_fvg > 0, high, 0), 30)} Essentially, if this condition bearish_fvg > 0 is met I want to return High else 0 and I want the sum of it over 30 days so that i can average it. Thanks a lot.

Fetcher[ /I have noticed that many of you write two filters of the same condition. For example, one filter is written for stocks that crosses above its 20-day moving average and another filter is written for stocks that crosses below its 20-day moving average. Why not just write one filter that would allow both conditions to be met but also informs you which is which. Here's how you write it. code set{condition 1, count(indicator 1, indicator 2,1) 1} set{condition 2, count(indicator 1, indicator 2,1) * -1} set{both, condition 1 + condition 2} set{result, 1 - count(both equals 0,1)} result above 0 add column both{result} Hence, taking the above example of 20-day moving average crossover:/ set{up, count(price crossed above MA(20),1) 1} set{down, count(price crossed below MA(20),1) * -1} set{both, up + down} set{Xover, 1 - count(both equals 0,1)} Xover above 0 add column both{Xover} ]

njjstocks 8 posts msg #161241 - Ignore njjstocks	7/16/2024 4:39:24 AM Thanks both for the pointers. Here's the implementation for the psudo logic above set {if, count(bear_fvg_check > 0 ,1)} set {then, bear_fvg_check * high} set {bear_fvg_sum, sum(then, 30)}
