Moving Average Uptrend >= 20 days

[bullman1083]

Hi guys, trying to find a simpler way to code that the 200 day Moving average has been in an uptrend for at least 20 days and also add that the stock has not declined more than 50% in the past 5 yrs. here's what i have so far for the 200DMA...


#200D sma 1month uptrend indicator

def smaup = simplemovingAvg(close,200) > simplemovingAvg(close,200)[1] and simplemovingAvg(close,200)[1] > simplemovingAvg(close,200)[2] and simplemovingAvg(close,200)[2] > simplemovingAvg(close,200)[3] and simplemovingAvg(close,200)[3] > simplemovingAvg(close,200)[4] and simplemovingAvg(close,200)[4] > simplemovingAvg(close,200)[5] and simplemovingAvg(close,200)[5] > simplemovingAvg(close,200)[6] and simplemovingAvg(close,200)[6] > simplemovingAvg(close,200)[7] and simplemovingAvg(close,200)[7] > simplemovingAvg(close,200)[8] and simplemovingAvg(close,200)[8] > simplemovingAvg(close,200)[9] and simplemovingAvg(close,200)[9] > simplemovingAvg(close,200)[10] and simplemovingAvg(close,200)[10] > simplemovingAvg(close,200)[11] and simplemovingAvg(close,200)[11] > simplemovingAvg(close,200)[12] and simplemovingAvg(close,200)[12] > simplemovingAvg(close,200)[13] and simplemovingAvg(close,200)[13] > simplemovingAvg(close,200)[14] and simplemovingAvg(close,200)[14] > simplemovingAvg(close,200)[15] and simplemovingAvg(close,200)[15] > simplemovingAvg(close,200)[16] and simplemovingAvg(close,200)[16] > simplemovingAvg(close,200)[17] and simplemovingAvg(close,200)[17] > simplemovingAvg(close,200)[18] and simplemovingAvg(close,200)[18] > simplemovingAvg(close,200)[19] and simplemovingAvg(close,200)[19] > simplemovingAvg(close,200)[20] ;

goodness me...
let's be a bit more efficient...

input uptrend_length = 20;
def ma = simplemovingAvg(close,200);
def up_down_day = if ma > ma[1] then 1 else 0;
def in_uptrend = if sum(up_down_day, uptrend_length) == uptrend_length then 1 else 0;

# 252 days per trading year
input years_back = 5;
def days_back = years_back * 252;
def low_point = lowest(close, days_back);
def fixed_point = close[days_back];
def drawdown_ok = if low_point >= fixed_point * 0.5 then 1 else 0;

plot hit = if in_uptrend == 1 AND drawdown_ok == 1 then 1 else double.nan;

I wasn't sure how you want to calculate the max drawdown. This is calculated against the price at close of day, 5 years ago. It does not look through the days in order at all; it does not look for a high before a low and calculate half of that high as a minimum point. It is a starting point for you more than anything else.

Is there a way to code it so that it looks from 5yrs back to present and to look for a high then a low as the stock declines?

The scan you are thinking of is simple to conceptualize in a sequential world -- we look at a chart and find a high and then look to the right of that high for a low. This is the way that traders have come to look at charts, and it is easy to understand. Thinkscript is not really a sequential language in that way. It is not so easy to program it to look for a high, and then a low. It can find highs, and lows, but which came first is more difficult. There are, of course, ways to do it but they can be cumbersome, or require artificially defined 'zones' (find a stock where the highest high happened between 5 and 2 1/2 years ago and the lowest low happened between 2 1/2 years ago and now).

Thinkscript is a capable language and makes some great tools, but learning to think thinkscript is not straight forward, especially as most everything else we do in trading is sequential.

Not so helpful, perhaps. Hopefully informative.
