Subhag Ghosh Trend Signal For ThinkOrSwim

Luna said:
Hey @samer800 excellent job!! I found this script on TV and it seems fairly easy to covert, but I am breaking my head over this. If you could help with this, I would really appreciate it!!! Thank you in advanc!

This is the script:

//Trend Analyzer can be used in gauge the market underlying current.
// Use 3x to 4x higher time frame and trade in direction of the trend.
// e.g. If you are trading on 3 min chart and you can set indicator time frame to 15 min, if you see the indicator is buy, you should look for buy opportunity instead of sell and vice versa.

//@version=3
study("Subhag Ghosh Trend Signal", overlay=false)
ha_t = ticker
col_red = #ff0000
col_green = #00ff00
fast_length = input(title="Fast Length", defval=3)
slow_length = input(title="Slow Length", defval=10)
src = input(title="Source", defval=close)
res_60 = input('15', title="Higher Time Frame 1 ")
trend_60 = security(ha_t, res_60, ((ema(src, fast_length) - ema(src, slow_length))/src)*100)
prev_trend_60 = security(ha_t, res_60, ((ema(src[5], fast_length) - ema(src[5], slow_length))/src[5])*100)
trend_status_60 = trend_60 > prev_trend_60
plot(1, title="Trend Visualizer", color=(trend_status_60 ? col_green : col_red), linewidth=24, transp=0)

check the below. I added options to change the mov avg type and aggregation.

def trend_status_60 = trend_60 > prev_trend_60;
plot "0" =  if isNaN(close) then na else 0;
"0".AssignValueColor(if trend_status_60 then Color.GREEN else Color.RED);

expected to have some discrepancies between TV and TOS since both handle the data source differently. may someone can look to the code further.

I just did minor change in the code below you may try. I added lookback period option so you can adjust mom length. :)

@samer800 - Yes! Thank you :) .. The screenshot that I posted is from TV - source code definitely could use a facelift.
TBH Nadaraya-Watson: Rational Quadratic Kernel is more reliable.
