How can I explain it what should be coded.

If I lose 1 trade, then the position size should be calculated, which leads to the capital growing by 1% when the take profit of the trade is reached.

Example

Capital = 100%
1.trade ordersize = 1
Trade won, capital = 100.2%
set capital 100.2% to capital 100%

Capital = 100%
2nd Trade Ordersize = 1
2.trade won, capital = 100.7%
set capital 100.7% to capital 100%

capital = 100%
3rd Trade Ordersize = 1
3. trade lost, capital = 99.2%

capital 99.2%
4th trade calculate order size for the 4th trade so that when the take profit of the trade (1.5%) is reached, the capital rises to 101%.
4th trade lost, capital = 88.9%

capital 88.9%
5th trade calculate order size for the 5th trade so that when the TakeProfit of the trade (1.5%) is reached, the capital rises to 101%.
5th trade won, but capital only 99.1%

capital 99.1%
6th trade calculate order size for the 6th trade so that when the TakeProfit of the trade (1.5%) is reached, the capital rises to 101%.
6th trade won, capital 100.4%
set capital 100.4% = 100%

capital = 100%
7.Trade Ordersize = 1
……

general:
as long as capital > capital [1] should capital = 100%
as long as capital < last 100% order size is to be calculated in such a way that with this order size and with reaching the TakeProfit of the trade here = 1.5% the capital rises on 101%.

Hello Roberto-

A big thank you for being on the road for me again and doing work.
It looks quite excellent, but it seems to me to be a bug that I can’t program away. But we are already very close to the solution.

With lines 28-33 we at myProfit set > 0 the equity to 100%. Clear.

But we also need to check whether myProfit >0 and the new capital exceeds 100%. We must not set the capital to 100% after each trade won, but only when we have won the trade and the last reached 100% are exceeded!

I think I have caught all imaginable combinations with the following example.

Example

Capital = 100%
1st trade ordersize = 1
Trade won, capital = 100.2%
set capital 100.2% to newCapital 100%

newCapital = 100%
2nd Trade Ordersize = 1
2.trade won, capital = 100.7%
set capital 100.7% to newCapital 100%

newCapital = 100%
3rd Trade Ordersize = 1
3. trade lost, capital = 99.2%
// do not set to 100%

newCapital 99.2%
4th trade calculate order size for the 4th trade so that when the take profit of the trade (1.5%) is reached, the capital rises to 101%.
4th trade lost, capital = 88.9%
// do not set to 100%

newCapital 88.9%
5th trade calculate order size for the 5th trade so that when the TakeProfit of the trade (1.5%) is reached, the capital rises to 101%.
5th trade won, but capital only 99.1%
// do not set to 100%

newCapital 99.1%
6th trade calculate order size for the 6th trade so that when the TakeProfit of the trade (1.5%) is reached, the capital rises to 101%.
6th trade won, capital 100.4%
set capital 100.4% to newCapital = 100%

newCapital = 100%
7th Trade Ordersize = 1
7th trade lost, capital = 99.5%

newCapital 99.5%
8th trade calculate order size for the 8th trade so that when the TakeProfit of the trade (1.5%) is reached, the capital rises to 101%.
8th trade won, TakeProfit is reached, capital now 101%
set capital 101% to newCapital = 100%

newCapital = 100%
9th Trade Ordersize = 1
….

Hello Roberto.

Thank you for your work. Your code unfortunately does not work yet in the sense I wanted. It is hard for me to express correctly and for you it is guaranteed not easy to understand me. Therefore I ask you, that we create the code piece by piece. Maybe the other one from here can help too.

The task is: We code a money management system for a trading system that works with time stop.

We first hide everything else. We only want to calculate the position size needed to increase the initial capital in 1% when the trade reaches the TakeProfit of 1.5%.

Can you code this or is someone else from here trying first.
(It has time, Rome was not built in a day either. Maybe weekend to weekend. I look in once every 2nd,3rd day).)

// late lunch trade with money management system

defparam cumulateorders = false
defparam flatafter      = 213000
 
once Capital    = 10000
once OrderSize  = 1
once LotSize    = ordersize
 
td = opendayofweek >= 1 and opendayofweek <= 5
tt = time = 133000 
c  = close > exponentialaverage[6](close)

lotsize = ??? // that´s the question

If td and tt and c then
buy lotsize at market
endif


set target %profit 1.5

Hello Roberto.
You did it in seconds! Thank you very much!

But it is not what you are looking for! Line 15 comes too early!
We do not check yet whether the StrategyProfit > StrategyProfit[1] is! !!

No, we want to calculate only first the position size, which is needed to increase the Capital by 1%, if the TakeProfit of the trade of 1.5% is reached.
It is (first) (completely) irrelevant whether StrategyProfit>StrategyProfit[1] is.

I am very sorry that we have misunderstood each other so far.

Because we work with a time stop! Time stop!!

The takeprofit is reached rather in few cases
