Hello Seref,

Regarding the first strategy, it depends on when it starts making profit. If you are using shorter periods for testing, it is important to notice if the strategy starts making profit from a place where the backtester starts calculating on a new shorter period. Such case may mean that the pessimistic scenario of the backtester is "too pessimistic". You can try the Comparator tool. If this is not the case, the strategy may change from sharp profit to sharp loss very rapidly. You may give it a chance for 2-3 deals with minimum amount, but if it doesn't go on profit, you should probably remove it from the portfolio.

For the second strategy, even small gradual profit is a good sign. You can run both strategies if you like.

The real problem is not when to start trading a strategy, but when to stop trading it.

A good idea is to measure the strategy performance on the trading account. If it makes losing trades just from the beginning, you can remove it for a better time. If recovers in some time (on a backtest), you can return it back.

If a strategy trades evenly with consecutive profits and losses, it may be a note that the strategy can be improved for a better performance.

If a strategy makes a profit, you can use it until it goes well. If it starts failing, you have to remove it before losing the profit it has made.
