In trading, this is a game of probabilities, you try to predict one or the other event, in a local time frame, based on incomplete information.
Obviously, there are too many things that you cannot control, which means this can be attributed to unforeseen risks. However, you can control some things, for example, the percentage of the deposit to transactions.
Exactly, while it is not too late don't add more leverage or funds for covering margin requirements. Depositing more and trying to chase loss is like playing with fire, you will burn more capital and risks will be doubled. Predicting long-term trends is easy rather than playing with technical analysis tools on small time frames, managing risks should be easier on weekly charts too compared to 15 minutes timeframe. The weekly timeframe and upper levels are best for analyzing the long-term trend, patience is a real money-making machine for this timeframe traders. At least you will spend only few hours per week to see what is going on the high levels of market.
